Frozen Heart
The 0.15 launch notes explicitly list Ice Cap Mushrooms + Cobalt + Heart Beet as the materials used to make the Frozen Heart. Equip it for Freezing immunity. This is current launch-note evidence, not an old wiki recipe carried forward.
Snow Dungeon boss
The current boss has four body pieces. During an attack it takes one piece and tries to crush you with it; that attacking piece becomes the weak point. Destroying all four pieces ends the fight.
Current EA gameplay also shows the dungeon/Compendium route using large snowballs and a top hat at the boss pedestal. The old Alpha 0.9 note describes the same summon pattern, which gives this mechanic cross-version support — but the current footage is what upgrades it from “old wiki trivia” to current-build evidence.
What unlocks next
The Ice Pickaxe is the key progression reward/tool tier because official 0.15 notes say it can mine Palladium. Palladium then feeds the Desert chapter.
