HORDA ZERO
Ice Colossus is the boss associated with Glacial Peak.
Normal campaign A0 keeps the simpler legacy boss loop. BossEncounterCatalog is activated for Ascension above A0, while the Expedition capstone boss always uses the advanced phase runtime even at A0.
Advanced phase 1 starts at 70% HP and repeats every 4s after its 1s telegraph. After a 1 s telegraph, fires 3 fan projectiles (center and ±0.22 rad), speed 240, at 65% of boss damage. Arena effect: No additional arena effect.
Advanced phase 2 starts at 42% HP and repeats every 6s after its 1s telegraph. Creates 7 Void zones on a radius-132 ring; each zone has radius 42, lasts 2.4 s, and deals 42% of boss damage. Arena effect: Creates a storm/Void zone on the target: radius 80, 1 s warning, 0.3 s duration, 50% boss damage.
Advanced phase 3 starts at 18% HP and repeats every 3s after its 1s telegraph. On first activation, permanently increases boss speed and damage by 15% for the encounter. Arena effect: No additional arena effect.
