Support
4: Standard carry slot. Fires after debuffers and AOE heroes have applied their effects, maximising the value of Hunting’s +16% DMG bonus on a target already softened by teammates.
5: Alternative back-row slot when another carry needs pos 4. Still fires Hunting effectively. Slightly later in Super Core cycle but otherwise equivalent.
3: Fires earlier but before debuffers have applied their effects. Less optimal for Hunting’s damage bonus since fewer teammates have softened the target.
Kelly is the most dangerous single-target assassin in Last Fortress, targeting the lowest-AGI enemy (typically the opposing team’s backrow carries) and delivering devastating burst damage with a 50-100% chance for a second action each round via Spine Whip UW. Her Cat Soul exclusive gear progressively shreds target DMG Mitigation by 7% per action (stacking 3 times), then applies Coma for 1 round when the cap is reached. With Hunting adding +16% DMG to the target for the entire round and Zealous granting +2% DMG Bonus to all allies, Kelly is both an elite carry and a passive team damage amplifier.
Pros & Cons
- Spine Whip UW grants 50-100% chance for a second action each round (guaranteed after 2 rounds without one), giving Kelly the highest sustained single-target DPS in the game.
- Hunting targets the lowest-AGI enemy, automatically sniping the opposing team’s most valuable backrow carries who typically have low AGI.
- Cat Soul exclusive gear shreds target DMG Mitigation by 7% per action (stacks 3, max 21%); at cap, clears stacks and applies Coma for 1 round, stunning the target.
- Zealous grants +2% DMG Bonus to all allies passively, making Kelly a team damage amplifier simply by being in the lineup.
- Serpent Whip (Elite UW) grants all male characters +15% DMG, a significant team-wide buff in lineups with male heroes like Roland, Galande, Harman, and Bolton.
- Hunting’s lowest-AGI targeting is predictable — opponents can manipulate AGI stats to redirect Kelly’s attacks to expendable heroes or high-DEF tanks.
- No AOE capability; Kelly can only kill one target at a time, making her ineffective at clearing multiple threats simultaneously.
- Low VIT (299) makes her fragile; she is often targeted by opposing Kellys or Galandes who seek the lowest-HP or lowest-AGI backrow hero.
- No self-sustain or shielding; relies entirely on teammates for survival between her lethal turns.
Skills
Kelly wields her whip, dealing 132/150/168/185/220% WPN DMG to 1 enemy.
+4/4.8/5.6/6.4/8% WPN DMG Bonus and +2.5/3/3.5/4/5% Initiative for this Hero
+1/1.2/1.4/1.6/2% DMG Bonus for all allied Heroes.
Deals 40/48/56/64/80% extra WPN DMG when casting "Sweet"
Attack the enemy with the lowest AGI, increasing the damage on this target in this round by 8/9.6/11.2/12.8/16%
Gear
Cat Soul is non-negotiable best-in-slot — the DMG Mitigation shred and Coma mechanic define Kelly’s identity as a single-target assassin. Resolute is mandatory for survivability. Reaper is the strongest offensive alternative, directly synergising with Kelly’s tendency to fight already-wounded targets. Pair Cat Soul + Resolute as the standard setup.
Exclusive set. 2-piece reduces target DMG Mitigation by 7% per action (stacks 3); at cap, clears and applies Coma for 1 round. 4-piece grants +15% Focus skill DMG per Focus skill cast (stacks 4, max +60%). Both effects compound Kelly’s already massive single-target output.
#1 Best
Standard DPS survivability set. +0.4% ATK per 1% HP lost. 4-piece death immunity with 30% HP restore and +50% DMG on the next attack. Essential for Kelly’s 299 VIT stat line.
#2
+15% Crit Rate and +30% Crit Damage. Kelly attacks twice per round via Spine Whip — more attacks mean more chances to crit. Strong in Buri lineups with Frosty Coffin crit bonuses.
#3
+10% ATK and +35% DMG after defeating target. Kelly’s Spine Whip double-action makes kills likely each round; Death’s +35% post-kill bonus amplifies the second hit.
#4
Normal attacks cause bleeding. Adds sustained damage between skill casts. Triggers Blaze Shark in Heytex lineups. Early game option before better sets are available.
#5
+10% DMG Bonus and +25% DMG to targets below 50% HP. Kelly frequently fights targets she has already softened in previous rounds — Reaper’s below-50% bonus activates consistently.
#6
Kelly is a STR-based single-target carry. Prioritize STR and damage stats on weapon and jewelry (offensive slots), and HP/DEF/VIT on helmet and body (defensive slots). AGI on the helmet is unusually important for Kelly — it directly affects whether she becomes the target of an opposing Kelly’s Hunting. Do not roll INT or TAC ATK substats.
DMG Bonus, STR, Crit Rate
DMG Bonus is a universal multiplier. STR scales WPN ATK for all of Kelly’s damage skills. Crit Rate amplifies her frequent attacks from Spine Whip double-action.
HP%, AGI, VIT
Survivability stats. HP% is the most efficient. AGI is critical for Kelly — higher AGI makes her less likely to be the lowest-AGI target of an opposing Kelly.
DEF, VIT, DMG Mitigation
Pure defense. Kelly’s 299 VIT makes her extremely fragile; every point of DEF extends her survival window for additional Spine Whip double-actions.
DMG Bonus, STR, Skill Effect Enhancement
DMG Bonus multiplies everything. STR scales damage. Skill Effect Enhancement boosts Sweet and Mysterious multipliers.

Beast 
Dual-sniper lineup with two single-target carries. Crimson Predator’s ATK, DMG Bonus, and Crit Rate feed both Kelly and Galande’s large single hits.
Primary tank. Scarlet Authority UW makes the lineup deal +10% more DMG and receive +10% more healing/shield. Watchers Leader grants +6% DMG Mitigation and +2% HP to all Watchers. Duke exclusive gear grants all Watchers +4% DMG.
Flaming Strike hits 3 back-row enemies, softening targets below 50% HP for Galande’s Conviction. Wolf exclusive gear provides death immunity at 5 Pledge layers. Scarlet Wolf adds +15% TAC DMG and +5% DMG Mitigation.
Secondary carry. Targets lowest-HP enemy. Conviction makes enemies below 50% HP take +10% more damage. Execution chains bonus 160% WPN DMG attack on kill. Execution gear ignores 30% DEF.
Primary carry. Targets lowest-AGI enemy. Spine Whip UW gives 50-100% chance for a second action each round. Cat Soul shreds target DMG Mitigation by 21% over 3 actions then stuns. Elegant adds +8% WPN DMG and +5% Initiative.
Drone shields protect the lowest-HP ally. Pinky Silhouette UW clears status effects and makes drone-hit enemies take +20% more damage. Drone exclusive gear has 30% chance for extra drone generation.
Classic Watchers dual-sniper lineup. Kelly targets the lowest-AGI enemy while Galande targets the lowest-HP enemy, splitting focus across two priority targets. Roland provides Watchers faction buffs and front-line tanking. Laurel handles AOE back-row damage to soften targets below Galande’s 50% HP threshold. Penny provides drone shields, healing, and the +20% damage taken debuff from Pinky Silhouette UW. All 5 Watchers for maximum +20% ATK/HP faction bonus.
Beast
Triple-sniper lineup wants maximum offensive stats. Crimson Predator’s ATK, DMG Bonus, and Crit Rate benefit all three damage dealers.
Budget tank. Castle provides front-line shields. Tough Wall adds DMG Mitigation and HP restoration on hit. Available from early game.
Primary healer. Battlefield Medic restores HP to the lowest-HP ally. Hurricane provides +8% TAC DMG and +24% Focus DMG. Available from Season 0.
Snipes lowest-AGI enemy with 220% TAC DMG focus skill. Parallel targeting with Kelly (both target lowest-AGI but Rebecca uses TAC DMG while Kelly uses WPN DMG).
Primary carry. Early game without Cat Soul — Reaper provides +25% DMG to targets below 50% HP, synergising with Rebecca’s softening. Apocalypse adds crit chance. Spine Whip double-action carries fights.
Third single-target damage dealer. Budget option available from early game. Reaper and Apocalypse provide straightforward damage boosts.
Budget-friendly early game lineup using commonly available heroes. Kelly and Rebecca provide dual single-target damage, Kin Ogawa adds a third sniper. Lunn tanks with Castle + Tough Wall for front-line durability. Suzuki Ren heals and provides Hurricane DMG bonus. No faction bonus (mixed factions) but all heroes are obtainable without spending, making this the best F2P starter lineup.
Beast
Triple-carry lineup with Kelly, Heytex, and Victoria. Crimson Predator’s offensive stats maximise damage output across all three.
AC Shield UW gives 200% max HP shield at battle start, immediately charging Victoria’s Energy Detection. Super Core accelerates focus from pos 1. Alpha Bless provides team-wide round 1 shields and crit immunity.
Staunch Will shields all allies every skill cast, feeding Victoria’s Energy Detection and Combat Master stacks. Chimera Anchor UW deals chip damage per shield event. Guardian INT scales shield size with rounds elapsed.
Independent assassin. Targets lowest-AGI enemy regardless of what Victoria does. Spine Whip double-action. Cat Soul shreds target DMG Mitigation. Serpent Whip (Elite) grants +15% DMG to all male heroes (Bolton, Harman, Heytex).
AOE carry. Marks 3 random enemies. Pinpoint Aim makes marked targets take +8% more damage, amplifying both Kelly’s and Victoria’s hits on marked targets. Blaze Shark procs from Minutemen synergy.
Shield-scaling carry. Energy Detection copies shields from Bolton, Harman, and Alpha Bless. Lightsword adds 250% of shield as burst damage. Thunder Blade UW gives +200 Focus, +15% DMG in back row.
Kelly and Victoria as dual carries in a shield-stack lineup. Bolton’s AC Shield and Harman’s Staunch Will feed Victoria’s Energy Detection for Lightsword burst, while Kelly independently assassinates the lowest-AGI enemy. Heytex provides AOE pressure and Pinpoint Aim’s +8% damage taken on marked targets benefits both carries. Three Minutemen (Bolton, Harman, Heytex) give +10% faction bonus while Kelly and Victoria bring raw Watchers power.
Synergies
Kelly targets the lowest-AGI enemy; Galande targets the lowest-HP enemy. Different targeting ensures they attack separate priority targets simultaneously, preventing the enemy from protecting both. Both are Watchers, contributing to faction bonuses.
Kelly and Victoria cover different carry roles — Kelly assassinates the most dangerous backrow hero via AGI targeting while Victoria delivers shield-scaled burst to a separate target. Cat Soul’s DMG Mitigation shred on Kelly’s target stacks with Victoria’s Melt Armor on hers, creating two simultaneous kill threats.
Heytex’s Pinpoint Aim makes marked targets take +8% more damage. If Kelly’s lowest-AGI target happens to be marked, her already massive hits deal 8% more. Heytex’s AOE clears the field while Kelly executes priority targets.
Roland’s Scarlet Authority UW makes the entire lineup deal +10% more DMG and receive +10% more healing/shield. Duke exclusive gear adds +4% DMG to all Watchers. Both buffs directly amplify Kelly’s single-target output.
Penny’s Pinky Silhouette UW makes drone-hit enemies take +20% more damage for 2 rounds. If Penny’s drones hit Kelly’s target, Kelly’s Spine Whip double-action deals +20% more damage on both hits, dramatically increasing kill probability.
Interactions with other heroes’ ultimate weapons.
Scarlet Authority makes the lineup deal +10% more DMG. Watchers additionally get +50% skill effects, boosting Kelly’s Sweet and Mysterious multipliers. The +10% healing/shield received also keeps Kelly alive longer through Penny’s drones and Harman’s shields.
While Link of Life is active, all allies gain +15% crit rate and +30% crit damage. Kelly attacks twice per round via Spine Whip — more attacks mean more crits. The combined crit bonus turns her high volume of hits into consistent critical strikes.
Drone-hit enemies take +20% more damage for 2 rounds. Combined with Cat Soul’s 21% DMG Mitigation shred and Hunting’s +16% DMG to the target, Kelly’s effective damage multiplier against a drone-debuffed target is enormous.

Counters
- High-AGI tanks in backrow (Hard Counter) — Opponents can place a high-AGI expendable hero in the backrow to bait Kelly’s Hunting. Since Hunting always targets the lowest-AGI enemy, manipulating AGI stats can redirect Kelly’s attacks to a tank or expendable hero, wasting her turns.
- Buri (Soft Counter) — Buri’s Link of Life distributes 50% of incoming damage across all heroes. Kelly’s single- target burst is diluted across the entire enemy team, preventing her from killing the target before damage distribution heals it back through sustained Link mitigation.
- Ada (Soft Counter) — Ada’s Reviving heals the entire enemy team passively every round. Targets that Kelly softens can be healed above kill threshold before her next Spine Whip turn, neutralising her sustained pressure.
- Low-AGI backrow carries (Hard Counter) — Heroes like Heytex (AGI 594), Rebecca (AGI 594), and other backrow carries with mediocre AGI are Kelly’s primary targets. She automatically hunts them via Hunting’s lowest-AGI targeting and can kill them in 1-2 rounds with Spine Whip double-action.
- Fragile lineups without shields (Soft Counter) — Without shields to absorb Kelly’s hits, fragile heroes die to her Spine Whip double-action in a single round. Cat Soul’s DMG Mitigation shred compounds across rounds, making even moderately durable targets vulnerable by round 2-3.
- Healerless lineups (Soft Counter) — Kelly’s sustained pressure via double-action and Cat Soul shred grinds targets down over multiple rounds. Without healing, her accumulated damage is permanent and the target inevitably dies.
Rating
S Tier. Kelly is an S-tier hero available from Season 0 and remains relevant through the entire game. Spine Whip UW’s guaranteed second action (100% if no second action for 2 rounds) gives her the highest sustained single-target DPS of any hero in the game. Hunting’s lowest-AGI targeting means she consistently kills the enemy’s most valuable backrow carries. Cat Soul’s DMG Mitigation shred stacks multiplicatively with other damage amplifiers. She is the longest-lasting S-tier carry in the game, viable from day one through late Dimensions.

Trivia
- Because Kelly automatically attacks the enemy with the lowest AGI even with normal attacks, and the enemy with the lowest AGI is most often a rear-line hero, Kelly is a strong hunter of offensive-type heroes rather than defensive-type heroes, allowing her to quickly clear out rear-line threats.
- She can ascend more easily than other S-grade heroes due to having higher recruitment odds. This makes her one of the most valuable heroes to ascend for quickly building a strong offensive line.
