Normalized against game maximums
Element Resistances
| Fire | Ice | Lightning | Poison | Best Element |
|---|---|---|---|---|
| 50 | 50 | 55 | 35 | Poison |
High fire/ice resist (50) and very high lightning (55). Only poison at 35 is exploitable.
Skills & Attack Patterns
| Skill | Type | Damage | Range | Cooldown | Effect |
|---|---|---|---|---|---|
| Fire Ball | Basic Attack | 10% ATK | 8 tiles | 1.0s | Ranged projectile, minor knockback |
| Immunity Combo | Active (51–99% HP) | — | Self | 45s | 2s of +200 debuff resist, +50 DMG resist. Effectively immune to all CC and damage. |
| Immunity Combo | Active (0–50% HP) | — | Self | 45s | Same invulnerability window, repeats in Phase 2 |
| Rapid Fire | Active | 20% ATK + 35% Fire | 8 tiles (AoE r=2) | 20–30s | Burst of fast fireballs in an area |
| Polymorph | Active | — | All enemies | 25–30s | Transforms heroes into chickens. 65% for 10s, 50% for shorter, 35% for full disable (no move/attack/skill). Fight-defining ability. |
| Silence Curse | Phase (0–35% HP) | 50% Lightning | Jump | One-time | Permanent curse: whenever cursed target uses a skill, triggers a lightning strike on them. |
Passive Abilities
| Passive | Trigger | Effect |
|---|---|---|
| Auto-Fire | Always active | Fires an extra fireball every 0.5s automatically (separate from basic attack) |
| Crit Retaliation | After being crit 10 times | Triggers a burst of rapid fire balls. Low internal CD (0.17s). More crits = more retaliatory burst. |
| Teleport Blink | When attacked | 5s CD teleport to random location. Makes Grimhild extremely hard to pin down. |
Grimhild teleports every 5 seconds when attacked. Your melee DPS will constantly lose uptime chasing her. Ranged builds are significantly better.
Phase Transitions
| HP Threshold | Event |
|---|---|
| 100–51% | Normal combat. Immunity Combo every 45s. Polymorph every 25–30s. |
| 50% | Summons 3 Puppets. Immunity Combo resets. Polymorph continues. |
| 35% | Silence Curse — one-time permanent debuff. Every skill cast triggers a lightning strike on the caster. |
Puppet Summons (Phase 2 — 50% HP)
| Puppet | Model | HP | ATK | DEF | Speed | Resists | Behavior |
|---|---|---|---|---|---|---|---|
| Spider Puppet | spider_01 | 2.5 | 1.1 | 1 | 5 | All 10 | Melee + leap attack (80% Fire, 40% stun). Easy to kill. |
| Bear Puppet | bear_01 | 1.3 | 1.1 | 2 | 4 | All 10 | Melee + poison aura (30% Poison per tick). Easy to kill. |
| Golem Puppet | stone_02 | 6 | 1.1 | 4 | 2 | 40/40/65/40 | AoE melee (60% ATK) + taunt aura every 6s. Very tanky. Strong vs lightning (65 resist). |
Priority: Kill Spider and Bear first (10 all resist = melt instantly). Golem is tanky (DEF 4, 65 lightning resist) but its taunt aura can actually help by redirecting aggro off your healer.
Optimal Team Comp
Grimhild's charm effect redirects attacks — Taunt overrides it. Rock Dragon's damage immunity at ★2 blocks Grimhild's one-shot mechanics.

Grimhild drains team HP with AoE dark magic. AoE heal + Boar King double-cast is the only way to keep 3 heroes alive simultaneously.

Physical damage bypasses Grimhild's 60+ element resists. Fear of Fear's ★4 permanent shadow form keeps DPS uptime high during charm phases.

Gem & Card Minimums
This is where gear requirements become strict:
| Requirement | Minimum | Why |
|---|---|---|
| DPS weapon gems | Lv4+ | Must beat enrage timer |
| DPS card | ★4 | ★3 cards cannot meet the DPS check |
| Tank HP gems | Lv4+ | Dark Wave hits through DEF — raw HP is the defense |
| Bench pet passives | Lv3+ | Every % matters at this difficulty |
Strategy Summary
- Ranged DPS only — Grimhild teleports every 5s. Melee DPS wastes half the fight chasing her.
- Survive Polymorph — 65% chance to chicken your heroes for 10s. Your tank MUST have enough HP to survive unaided during polymorph.
- Kill Spider + Bear puppets first — All 10 resist, they die instantly. Golem last.
- After 35% HP: minimize skill use — Silence Curse makes every skill cast trigger lightning on the caster. Auto-attack DPS becomes more valuable. Poison DoT ticks don't trigger the curse.
- Don't rely on CC — Immunity Combo gives her 2s windows of total invulnerability every 45s.
This is where F2P players hit the wall. Priority: (1) DPS weapon gems to Lv4-5, (2) ★4 card on DPS, (3) pet passives to Lv3. These three changes are usually enough.
