Mystic Gjallarhorn Effect and Basic Information

Basic Information

Skill
Mystic Gjallarhorn
Type
Mt 14 Range 2
Effect Accelerates Special trigger (cooldown count-1).
If defending in Aether Raids, at the start of enemy phase, grants 【Foresight Snare】 to allies closest to the bottom of the map within 3 columns centered on unit for 1 turn. If not defending in Aether Raids, at the start of enemy phase, if there is only one ally (excluding unit) with the highest Def among allies closest to foe, grants 【Foresight Snare】 to that ally for 1 turn.
For foes within 3 rows or 3 columns centered on unit, inflicts Atk/Def/Res-5 and neutralizes foe's bonuses to Atk/Def/Res during combat.
At start of combat, if unit's HP ≥ 25%, inflicts penalty on foe's Atk/Res = 20% of unit's Res at start of combat, unit deals +X damage (excluding area-of-effect Specials), and reduces damage from foe's attacks by X during combat (excluding area-of-effect Specials; X = number of allies within 3 rows or 3 columns centered on unit x 5; max 15), and restores 7 HP to unit after combat.
【Foresight Snare】
If foe initiates combat and there were no combat instances on the current turn yet (player phase and enemy phase are counted separately), triggers the following effects:
- Cancels foe's attack, ending their action.
- Inflicts 【Isolation】 and status preventing
counterattacks on foe through foe's next action.
- Cancels Foresight Snare granted to your army.
(These effect trigger after Aether Raids traps but before Savior; does not trigger in Pawns of Loki).
