Monica
Watcher’s Shield
Watchers
Advanced Elite
Tank
AOE Damage
1: Primary tank slot. Takes the most hits, maximising LumiShield damage recording and Ready to Battle’s +5% skill DMG per hit. Glorious Counterstrike’s 50% Stun procs most frequently from pos 1 since more enemies target this position.
2: Secondary tank slot. Still absorbs significant damage for LumiShield recording. Useful when another tank (Buri) holds pos 1 and Monica serves as a damage-absorbing off-tank.
3: Transition position. Takes fewer hits than front row, reducing LumiShield recording value. Only viable when the lineup has two dedicated front-line tanks and Monica provides back-row AOE retaliation.
Monica is a charging tank who absorbs incoming damage through her LumiShield and converts it into AOE retaliation, dealing 40% of all recorded damage to 3 random enemies at the end of each round. Her Ready to Battle passive grants +5% skill DMG per hit taken while charging, rewarding her for sitting in the front line and absorbing punishment. Ruby Shield UW grants +500 Focus and +20% Initiative at battle start plus a shield equal to 80% of her max HP for 1 round, making her one of the most durable turn-1 tanks in the game while Glorious Counterstrike’s 50% Stun chance on LumiShield counter-attacks provides crowd control that disrupts enemy carries.
Pros & Cons
- LumiShield records all damage taken while charging and deals 40% of it to 3 random enemies at round end, converting defensive absorption into AOE retaliation that scales with enemy aggression.
- Ruby Shield UW grants +500 Focus and +20% Initiative at battle start plus a shield equal to 80% of max HP for 1 round, making her extremely durable in the critical first round.
- Sword & Shield exclusive gear 2-piece applies a shield equal to 30% recipient max HP to the lowest-HP teammate while charging, providing team-wide protection from the tank position.
- Glorious Counterstrike gives LumiShield counter-attacks a 50% chance to Stun for 1 round, disrupting enemy carries who target Monica.
- Resurgence restores 20% of lost HP at round end, providing passive self-sustain that reduces reliance on dedicated healers.
- Burst damage that kills Monica before LumiShield charging completes wastes the recorded damage entirely, as the AOE retaliation only fires at round end.
- Anti-shield mechanics (Diesel) strip Ruby Shield UW’s 80% max HP shield, removing her turn-1 durability and leaving her vulnerable to early focus fire.
- LumiShield’s 40% damage conversion to 3 random enemies cannot be targeted, potentially hitting expendable heroes rather than priority targets.
- No offensive scaling from ATK stats — Monica’s damage output is entirely dependent on how much damage she absorbs, making her useless in fights where enemies ignore her.
Skills
Monica lifts her shield and enters a charging status, while keeping a record of the DMG she takes during the charging period. At the end of the round, she swings her sword to deal some DMG equal to 20%/25%/30%/35%/40% of the recorded DMG to 3 random enemy targets.
During the charging period, for every incoming attack she takes, the DMG dealt by the "Chargeable LumiShield" increases by 1%/2%/3%/4%/5%.
At the end of each round, restores 10%/12%/14%/16%/20% of her lost HP.
HP cap increases by 10%/12%/14%/16%/20%.
When the "Chargeable LumiShield" launches counter-attacks, 25%/30%/35%/40%/50% chance to Stun the target for 1 round.
Gear
Sword & Shield is non-negotiable best-in-slot — the teammate shield while charging and +30% DMG taken debuff on exit define Monica’s team utility. Super Core is the standard pairing for pos 1 to accelerate the entire lineup’s focus bars. Castle replaces Super Core when another hero holds the focus accelerator.
Exclusive set. 2-piece shields the lowest-HP teammate with 30% of their max HP while Monica charges, adding team utility. 4-piece makes enemies hit by LumiShield take +30% DMG for 2 rounds after Monica exits charging, amplifying the entire lineup’s follow-up damage.
#1 Best
Death immunity 4-piece ensures Monica survives a burst kill attempt during charging. Without Monica the lineup loses its primary tank and LumiShield damage recording.
#2
Accelerates focus bar fill from the front line. Monica’s +500 Focus from Ruby Shield UW combined with Super Core’s focus acceleration means she casts LumiShield quickly, entering charging status early to begin recording damage.
#3
+DEF and DMG Mitigation with HP restoration on hit. Stacks with Resurgence’s 20% lost HP restore for significant passive sustain while charging.
#4
At start of each round restores HP equal to 35% of Monica’s ATK. Keeps her HP topped up so she can absorb more damage while charging without dying.
#5
Front-line shield generation. Castle’s shields stack with Ruby Shield UW’s 80% max HP shield, creating layered protection that extends Monica’s charging duration.
#6
Monica’s entire value is in surviving and absorbing damage while charging. Every substat should prioritise HP%, VIT, DEF, and DMG Mitigation. Do not roll offensive substats like DMG Bonus, STR, or Crit Rate — Monica’s damage output comes from recorded incoming damage, not ATK stats.
HP%, VIT, DMG Mitigation
Monica is a tank — weapon substats prioritise HP and defense. HP% scales the size of Ruby Shield UW’s 80% max HP shield and Sword & Shield’s 30% max HP teammate shield. VIT is the direct HP stat. DMG Mitigation reduces damage taken while charging.
HP%, VIT, AGI
HP% remains top priority. VIT continues building the HP pool. AGI reduces incoming damage and helps Monica act earlier for faster LumiShield activation.
DEF, VIT, DMG Mitigation
Pure defense. Higher DEF and DMG Mitigation reduce the damage Monica takes per hit, extending charging duration and keeping Ruby Shield UW’s protection layer intact longer.
HP%, VIT, Skill Effect Enhancement
HP% and VIT maximise the HP pool. Skill Effect Enhancement increases LumiShield’s damage recording percentage and Resurgence’s HP restoration.

Beast 
Triple-carry lineup with Heytex, Amum, and Victoria all dealing heavy damage. Crimson Predator’s WPN/TAC ATK, DMG Bonus, and Crit Rate maximise output across all three carries. Monica’s tanking and Ada’s healing provide sufficient survivability.
Primary tank. Resolute’s death immunity is critical since Monica must survive through full LumiShield charging cycles — without it, burst damage kills her before the 40% AOE retaliation fires. Sword & Shield shields the lowest-HP teammate while charging and makes enemies take +30% DMG for 2 rounds after exiting, amplifying all three carries. Ruby Shield UW gives 80% max HP shield turn 1.
Core healer. Resolute ensures Ada survives burst attempts — losing the lineup’s only healer is catastrophic. Breeze applies Reviving to all teammates at battle start. God-Slaying Axe UW grants +10% DMG and +10% DMG Mitigation on Raging Roar, amplifying all three carries.
AOE carry. Resolute’s death immunity protects his fragile 299 VIT frame. Marks 3 random enemies with Bullet Rain. Pinpoint Aim makes marked targets take +8% more damage, amplifying Victoria’s Lightsword and Amum’s Predator. War Ender snowballs on kills.
Execute carry. Apocalypse’s crit rate and crit DMG synergise with Crimson Eye Claws UW’s scaling crit (up to +50% crit rate / +50% crit DMG at 100% HP lost), maximising kill probability on wounded targets. Wolf Pack adds +80% WPN DMG to Predator and team-wide DMG stacking on kills. Ada’s healing keeps Amum alive between executions.
Burst carry. Super Core accelerates focus bars across the lineup from position 5, helping all heroes fire skills faster. Combat Master converts shield stacks into +25% DMG at full stacks. Energy Detection copies shields from Monica’s Sword & Shield teammate shield. Thunder Blade UW grants +200 Focus at battle start and +15% DMG in back row.
Top-tier X4-X6 meta lineup pairing Monica’s LumiShield tanking with Ada’s Reviving sustain in the front row, enabling three back-row carries to deal uncontested damage. Heytex marks random enemies with Bullet Rain and triggers Pursue procs, Amum executes low-HP targets with Predator’s kill chain, and Victoria converts shield accumulation into devastating Lightsword burst. Despite no faction bonus, the raw synergy between Monica’s damage absorption, Ada’s team-wide healing, and three top-tier carries makes this one of the strongest lineups in the X4-X6 meta.
Beast 
Monica as primary tank benefits from Metallic Dragon’s defensive stats. HP, DEF, and DMG Mitigation extend charging duration and Ruby Shield UW’s survival window.
Primary tank. Ruby Shield UW provides 80% max HP shield turn 1. LumiShield records damage and retaliates at round end. Sword & Shield shields the lowest-HP teammate while charging. Super Core accelerates focus from pos 1.
Staunch Will shields all allies, feeding Victoria’s Energy Detection. Chimera Anchor UW deals chip damage per shield event. Alpha Bless provides round 1 shields and crit immunity.
Co-carry. Bounty marks provide team-wide buffs. Executioner kills restore 500 Focus for chain-kills. Sword & Shield’s +30% DMG taken debuff amplifies Macklin’s Executioner hits on debuffed targets.
Independent assassin. Targets lowest-AGI enemy. Spine Whip UW double-action. Cat Soul shreds target DMG Mitigation. Sword & Shield’s +30% DMG taken debuff stacks with Cat Soul’s shred for devastating effective damage amplification.
Shield-scaling carry. Energy Detection copies shields from Harman, Monica’s Sword & Shield teammate shield, and Alpha Bless. Lightsword adds 250% of shield as burst damage. Thunder Blade UW grants +200 Focus, +15% DMG in back row.
Monica as the primary tank with Victoria as the carry. Monica’s LumiShield absorbs damage while Sword & Shield’s 2-piece shields the lowest-HP teammate (often Victoria or Kelly). After exiting charging, the 4-piece +30% DMG taken debuff amplifies Victoria’s Lightsword and Kelly’s Cat Soul hits. Harman layers shields feeding Victoria’s Energy Detection. Kelly provides independent single-target assassination. Full 5 Watchers for +20% ATK/HP faction bonus.
Beast
Dual-tank lineup benefits from Metallic Dragon’s defensive stats. HP, DEF, and DMG Mitigation keep both Buri and Monica alive for extended charging and Link of Life duration.
Primary tank. Link of Life distributes 50% of incoming damage with +24% DMG Mitigation. Frosty Coffin grants +15% crit rate and +30% crit DMG. Distribution extends Monica’s charging duration in pos 2.
Off-tank. LumiShield records damage while Buri’s Link of Life reduces direct hits. Sword & Shield shields the lowest-HP teammate while charging. Castle provides additional front-line protection. Ruby Shield UW gives 80% max HP shield turn 1.
Staunch Will shields all allies, feeding Victoria’s Energy Detection. Alpha Bless provides round 1 shields and crit immunity. Chimera Anchor UW deals chip damage per shield event.
AOE carry. Marks 3 random enemies with Bullet Rain. Pinpoint Aim makes marked targets take +8% more damage. Buri’s damage distribution keeps him alive for sustained Pursue procs.
Shield-scaling carry. Buri’s damage distribution and dual-tank front line protect her from being sniped. Harman’s shields feed Energy Detection and Combat Master stacks.
Dual-tank lineup with Buri and Monica sharing front-line duties. Buri’s Link of Life distributes 50% of incoming damage across all heroes, extending Monica’s charging duration significantly since she takes less direct damage per hit. The distributed damage still counts toward LumiShield recording, meaning Monica records from both direct and distributed hits. Harman provides shields and healing support. Heytex and Victoria handle damage from the back row.
Beast
Multi-carry lineup with Samantha, Macklin, and Victoria. Crimson Predator’s offensive stats maximise damage output across the damage dealers.
Primary tank. Ruby Shield UW provides 80% max HP shield turn 1. Sword & Shield shields the lowest-HP teammate while charging, potentially triggering Samantha’s Hunter’s Instinct. Castle adds layered front-line protection.
Staunch Will shields all allies, feeding both Victoria’s Energy Detection and Samantha’s Hunter’s Instinct. Chimera Anchor UW deals chip damage per shield event. Alpha Bless provides round 1 shields and crit immunity.
AOE carry. Hunter’s Instinct gains Strangler from teammate shields >= 30% max HP. Monica’s Sword & Shield and Harman’s Staunch Will feed Strangler stacks. Sweeping Slash hits all enemies with accumulated Strangler layers for stacking damage.
Co-carry. Bounty marks provide team-wide buffs. Executioner kills restore 500 Focus for chain-kills. Sword & Shield’s +30% DMG taken debuff amplifies Executioner hits.
Shield-scaling carry. Energy Detection copies shields from Harman, Monica, and Alpha Bless. Lightsword adds 250% of shield as burst damage. Multiple shield sources keep Combat Master stacks at maximum.
Monica and Samantha share a powerful shield synergy. Monica’s Sword & Shield 2-piece generates shields on the lowest-HP teammate while charging, and Samantha’s Hunter’s Instinct gains a Strangler layer whenever a teammate gains a shield >= 30% max HP. Monica’s Ruby Shield UW and Sword & Shield shields can trigger Hunter’s Instinct, accelerating Samantha’s Strangler stacks for Sweeping Slash AOE. Harman adds more shields for both mechanics. Macklin and Victoria provide dual carry damage.
Synergies
Monica’s Sword & Shield 2-piece shields the lowest-HP teammate while charging. Victoria’s Energy Detection copies 50% of every shield applied to allies, meaning Monica’s teammate shields feed Lightsword burst. LumiShield counter-attacks can Stun Victoria’s target, preventing retaliation.
Harman’s Staunch Will shields all allies every cast, layering on top of Monica’s Ruby Shield UW and Sword & Shield teammate shields. The combined shield generation creates a defensive wall that extends Monica’s charging duration while feeding any shield-dependent carries in the lineup.
Samantha’s Hunter’s Instinct gains a Strangler layer whenever a teammate gains a shield >= 30% max HP. Monica’s Sword & Shield 2-piece shields the lowest-HP teammate with 30% of their max HP while charging, directly triggering Hunter’s Instinct. Monica’s shield generation accelerates Samantha’s Strangler stacks for Sweeping Slash AOE.
Tucker’s The Tucker Shield! gives all allies a shield equal to 25% max HP plus +20% ATK and +20% Speed for 2 rounds. The shield stacks with Monica’s Ruby Shield UW for massive combined protection, while the ATK buff increases LumiShield’s counter-attack damage indirectly through team damage amplification.
Roland’s Scarlet Authority UW grants +10% DMG and +10% healing/shield to the entire lineup. The +10% healing/shield directly amplifies Monica’s Resurgence HP recovery and Ruby Shield UW’s 80% max HP shield size. Duke exclusive gear adds +4% DMG to all Watchers.
Interactions with other heroes’ ultimate weapons.
Monica’s Sword & Shield 2-piece shields the lowest-HP teammate while charging. Victoria’s Energy Detection copies this shield, feeding Lightsword burst. Monica’s LumiShield counter- attacks can Stun targets that Victoria is trying to kill, preventing them from healing or retaliating between hits.
Every time a teammate gains a shield, Chimera Anchor deals 50% TAC ATK to a random enemy. Monica’s Sword & Shield 2-piece generates shields on the lowest-HP teammate every round while charging, triggering Chimera Anchor chip damage consistently alongside the regular shield events from Harman’s own Staunch Will.
Scarlet Authority makes the lineup deal +10% more DMG and receive +10% more healing/shield. The +10% healing/shield directly increases Monica’s Resurgence 20% HP restore and Ruby Shield UW’s 80% max HP shield size. Watchers additionally get +50% skill effects from Roland’s presence, boosting Monica’s LumiShield damage recording percentage.

Counters
- Diesel (Hard Counter) — Diesel’s anti-shield mechanics strip Ruby Shield UW’s 80% max HP shield, removing Monica’s critical turn-1 protection. Without the shield, Monica is vulnerable to burst damage before LumiShield charging can record significant damage.
- Burst damage lineups (Hard Counter) — LumiShield’s damage conversion only fires at round end. Burst lineups that kill Monica before the round ends waste all recorded damage. Her charging status provides no defensive bonus besides Ready to Battle’s skill DMG scaling, making her vulnerable to concentrated burst.
- Multi-hit lineups (Hard Counter) — LumiShield records ALL damage taken while charging. Lineups with many small hits (Heytex’s rockets, Benson’s AOE burns) generate massive recorded damage totals that Monica converts to 40% AOE retaliation at round end. More hits also mean more Glorious Counterstrike Stun chances at 50% per counter-attack.
- Sustained damage lineups (Soft Counter) — Sustained damage lineups that deal damage evenly across rounds play directly into Monica’s strengths. Resurgence restores 20% of lost HP each round, LumiShield records damage over time, and Ready to Battle accumulates +5% skill DMG per hit for escalating retaliation.
Rating
S Tier. Monica is an S-tier tank from Season X6 onward. Her LumiShield charging mechanic converts defensive play into offensive output — the more she is hit, the more damage she deals back. Ready to Battle’s +5% skill DMG per hit while charging scales her damage with the enemy’s aggression. Sword & Shield exclusive gear adds team utility by shielding the lowest-HP teammate while charging and making hit enemies take +30% DMG for 2 rounds after exiting charging. Her unique damage-absorption-to-AOE conversion, Ruby Shield UW’s exceptional turn-1 durability, and Sword & Shield’s team utility make her the most versatile tank in the game and earn her S-tier status.
