Utility
3: First back-row slot. Park Ji-Mi fills focus fastest here, enabling earlier Electronic Shield casts that protect the entire team. She benefits from being behind tanks while still filling focus quickly.
2: Secondary tank slot. Park Ji-Mi can function as an off-tank thanks to her shield providing effective HP. Preferred in lineups where the back row is filled with DPS heroes.
4: Standard back-row slot. Slower focus fill delays her team-wide shields, but she still functions here when pos 3 is occupied by a higher-priority DPS hero.
Park Ji-Mi is a Rare Watchers support who shields ALL allies with Electronic Shield, the only team-wide shield skill among Rare heroes. Her Heart of Guardian upgrade adds +18% WPN ATK to the shield value, and Lucky Dog provides +8% Initiative to the lineup. She is the most versatile Rare support and remains relevant into S3 as a budget shield provider.
Pros & Cons
- Electronic Shield applies a shield to ALL allies — the only team-wide shield among Rare heroes.
- Heart of Guardian adds +18% WPN ATK to shield value, significantly increasing shield strength.
- Lucky Dog provides +8% Initiative to the entire lineup, giving your team a speed advantage in every round.
- Strategic Gathering grants +20% Gathering Speed, valuable for resource collection content.
- Watchers faction pairs with Lunn, Kelly, and Suzuki Ren for strong early faction synergy.
- Shield value scales with WPN ATK, which is limited by Park Ji-Mi’s Rare-tier stats.
- No healing skill; shields are consumed and do not regenerate HP lost before shielding.
- No damage contribution beyond basic attacks — she occupies a lineup slot without dealing damage.
- Low VIT (299) makes her fragile if shields are stripped or bypassed.
- Outclassed by Epic support heroes with stronger shields and additional utility in S3+.
Skills
Bestows a DMG Shield on all allied Heroes (38/45/50/55/65% of WPN ATK)
+4/4.8/5.6/6.4/8% Initiative.
Lineup Gathering Speed +10/12/14/16/20% when gathering.
Casting "Electronic Shield" grants an additional Shield with 9/10.8/12.6/14.4/18% WPN ATK.
Gear
Heal is mandatory for Park Ji-Mi because +45% Healing/Shield effect directly amplifies every Electronic Shield cast. Castle is the best secondary option for personal survivability, especially in pos 2. Alpha Bless provides a complementary shield layer for maximum early-fight protection. Avoid DPS sets — Park Ji-Mi’s only value is shielding.
+10% HP and +45% Healing/Shield effect. The shield amplification directly increases Electronic Shield value for all allies. This is the single most impactful set for Park Ji-Mi’s core function.
#1 Best
Adds team-wide round 1 shields and +8% Crit Immunity. Stacks with Electronic Shield for double-layer shield protection at battle start. Strong when maximizing early-fight defense.
#2
+8% DMG Mitigation and 40% chance to block 60% of incoming damage. Keeps Park Ji-Mi alive longer so she can cast Electronic Shield multiple times per fight. Best for pos 2 placement.
#3
Park Ji-Mi’s shield scales with WPN ATK (STR-based), so weapon STR and Skill Effect Enhancement on jewelry are the offensive-adjacent substats that actually improve her support output. All other slots should prioritize pure survivability. Do not invest in DMG Bonus, Crit Rate, or INT.
HP%, STR, DMG Mitigation
HP% keeps Park Ji-Mi alive longer for more shield casts. STR scales her WPN ATK which directly determines Electronic Shield value. DMG Mitigation provides layered defense.
HP%, VIT, AGI
HP% and VIT for raw survivability. AGI reduces targeting from sniper skills that would otherwise eliminate Park Ji-Mi before she can shield the team.
DEF, VIT, DMG Mitigation
Pure defense substats. Park Ji-Mi must survive to cast — her shields protect everyone else, but she needs gear defense to protect herself.
HP%, Skill Effect Enhancement, DMG Mitigation
HP% for survivability. Skill Effect Enhancement directly boosts Electronic Shield value and Heart of Guardian’s +18% bonus. DMG Mitigation for additional personal defense.

Beast 
Defensive lineup built around damage mitigation and shields. Metallic Dragon’s HP, DEF, DMG Mitigation, and Crit Immunity bonuses maximize the frontline’s survivability, giving Park Ji-Mi more time to stack shields and Lunn more time to apply debuffs.
Primary tank. +11% WPN DMG Mitigation and Money for Power (-25% DMG Bonus for 2 rounds) combine to reduce incoming damage significantly. Lunn’s durability is enhanced by Park Ji-Mi’s shields absorbing damage before it reaches his HP pool.
Core support. Electronic Shield protects all allies including Lunn, extending the tank’s effective HP pool. Heart of Guardian adds +18% WPN ATK shield value. Lucky Dog +8% Initiative ensures shields land before enemies attack.
Off-tank and debuffer. Stacks debuffs with Lunn’s Money for Power for multi-layered stat reduction on enemies. Provides Watchers faction count and additional frontline presence from pos 3.
Primary carry. Targets the highest-AGI enemy, reliably hitting key carries. Park Ji-Mi’s shields keep Kelly alive while Lunn’s debuff weakens Kelly’s targets for faster kills.
Secondary sniper. Targets enemy backrow heroes for additional carry pressure. Park Ji-Mi’s shields keep Rebecca alive through return fire from the enemy back row.
A Watchers lineup combining Lunn’s debuffing tank with Park Ji-Mi’s team-wide shields. Lunn reduces enemy damage by 25% while Park Ji-Mi absorbs incoming damage with Electronic Shield. Kelly and Rebecca provide backrow DPS. Suzuki Ren adds debuff stacking from the front line. The lineup outlasts enemies through combined damage mitigation and shielding.
Synergies
Lunn’s +11% WPN DMG Mitigation reduces incoming damage while Park Ji-Mi’s Electronic Shield absorbs the remaining damage. The combination creates a double-layer defense where enemies must first overcome the shield, then deal mitigated damage to Lunn’s HP. Both are Watchers.
Victoria’s Lightsword damage scales with her accumulated shield value. Park Ji-Mi’s team-wide Electronic Shield feeds Victoria’s shield pool, directly converting Park Ji-Mi’s support into Victoria’s damage output. This synergy is relevant when Victoria enters the roster.
Park Ji-Mi’s Lucky Dog provides +8% Initiative to the lineup, helping Kelly act before enemy carries. Kelly’s AGI-targeting sniper skill benefits from acting first to eliminate the highest-AGI enemy before it contributes damage. Both are Watchers.

Counters
- Galande (Hard Counter) — Galande’s high burst damage can break through Park Ji-Mi’s shields and kill backrow heroes in a single hit. Shields are consumed instantly by high-damage single hits, negating Park Ji-Mi’s sustained protection model.
- Casino (Soft Counter) — Casino’s focus drain delays Electronic Shield, leaving the lineup unshielded during critical early rounds. Without her shields, Park Ji-Mi provides only the +8% Initiative passive — insufficient to justify a lineup slot.
- Multi-hit / chip damage lineups (Situational Counter) — Electronic Shield absorbs a fixed amount of damage regardless of hit count. Against lineups that deal many small hits (rockets, drones, DOTs), each hit is individually absorbed by the shield, making Park Ji-Mi’s protection extremely efficient per cast.
Rating
B Tier. Park Ji-Mi is the best Rare-rarity support hero. Electronic Shield is the only team-wide shield among Rare heroes, providing effective HP to all five teammates simultaneously. Heart of Guardian adds +18% WPN ATK shield value on skill, and Lucky Dog’s +8% Initiative gives the entire lineup a speed advantage. Rated B because her team-wide shield provides unique utility that no other Rare hero can replicate, extending her relevance into S3 as a budget support option.
