Normalized against game maximums

Element Resistances

Fire	Ice	Lightning	Poison	Best Element
55	55	55	55	Physical (bypasses all resist)

All resists are perfectly balanced at 55. No element has an advantage — physical damage or raw ATK scaling is best.

Phase Mechanic — Elemental Cycling

Guttorm is unique: he shifts between 3 elemental forms every 30 seconds in a fixed cycle.

Fire Form (30s) → Poison Form (30s) → Wind Form (30s) → Fire Form → ...

Each form has different skills and attack patterns but shares the same element resistances.

Phase 1: Fire Form (ID 3100020)

Stat	Value
HP Ratio	13 (highest)
Attack Speed	60 frames (1.0s)

Skills:

Skill	Type	Damage	Range	Cooldown	Effect
Fire Arrow	Basic Attack	15% ATK + 10% Fire	6 tiles	—	Ranged, 40% base crit, 25% chance to Stun (2s)
Explosive Arrow	Skill	100% ATK	9 tiles (AoE r=1)	6s	65% chance to Stun (2s), heavy knockback

Danger: Fire Form has the highest HP pool and heavy stun pressure. Your tank MUST hold aggro or the stuns will chain-lock your DPS/healer.

Phase 2: Poison Form (ID 3100021)

Stat	Value
HP Ratio	10
Attack Speed	60 frames (1.0s)

Skills:

Skill	Type	Damage	Range	Cooldown	Effect
Poison Arrow	Basic Attack	20% ATK	6 tiles	—	Ranged, 30% chance to Slow (ATK speed -60) for 6s
Poison Cloud	Skill	Summon	9 tiles	9s	Drops a 3x3 poison fog zone (DoT) at target location

Danger: The slow debuff (-60 ATK speed) cripples your DPS output. Poison clouds stack — don't let them overlap on your team.

Phase 3: Wind Form (ID 3100022)

Stat	Value
HP Ratio	10
Attack Speed	60 frames (1.0s)

Skills:

Skill	Type	Damage	Range	Cooldown	Effect
Wind Arrow	Basic Attack	10% ATK	6 tiles	—	Ranged, 50% base crit, self-buff: +5 ATK speed per hit (stacks 30, 20s)
Poison Cloud	Skill	Summon	9 tiles	9s	Same poison fog zone as Poison Form

Danger: Wind Form accelerates over time. Each basic attack gives +5 ATK speed (max 30 stacks = +150 ATK speed). If the fight drags, Wind Form becomes a machine gun. Kill fast or your healer can't keep up.

Adds

Guttorm summons minions (ID 3100024) with boosted stats:

HP +25%, DEF +100%, ATK +70% of Guttorm's base
Low priority — focus the boss unless adds are overwhelming your healer

Enrage Timer

Time	Effect
0–120s	Normal combat
120s	Enrage begins: +50% ATK, +100 DMG bonus, +30 ATK speed, +30 battle speed
Every 20s after	Stacks again (max 10 stacks)

At max enrage stacks: +500% ATK, +1000 DMG bonus, +300 ATK/battle speed. Effectively instant death for your team.

Optimal Team Comp

Tank

Howl Warrior

Why this hero

Must hold aggro through all 3 phases. Absorb stuns in Fire Form. Rock Dragon's DEF stacking compounds with Guttorm's predictable attack pattern.

Healer Mage

Why this hero

Boar King's double-cast heals keep tank alive through phase transitions. Resist shred from passives strips Guttorm's 55 element resist over time.

Volley Archer

Why this hero

Physical burst ignores Guttorm's 55 element resist entirely. Fear of Fear's shadow clones stack -ATK debuffs, reducing incoming damage for the whole team.

Gem Adjustments

No specific swaps needed. Use your standard PvE gem setup.

If your tank is dying in Wind Form (late fight with stacked ATK speed), upgrade their Emerald (HP) gems.

Strategy Summary

Hold aggro — Tank must taunt before each phase shift. Guttorm retargets on phase change.
Avoid poison clouds — Don't stack them on your healer. Reposition if needed.
Burst during Poison/Wind Form — These have lower HP ratio (10 vs 13). Fire Form is the tankiest.
Watch the clock — Enrage at 120s is generous, but Wind Form's self-buffing ATK speed stacks make late-fight healing brutal.

If you're stuck: The issue is gear, not strategy. Farm more Abyss floors for equipment upgrades. Guttorm is the tutorial boss.
