Kulve Taroth
Kulve Taroth wears a gold coat until a hunter breaks it off. While that coat is on, Thunder lands; after the coat sheds, Ice does. Pressure parts until the gold heats and falls — the elemental switch follows the shed, not the area change. The siege clears only when the horns break in the last area; earlier horn chips do not finish it. The Master Rank hunt is a slay before it escapes, not a horn-only clear.
