The Ice Bomb is a weapon added by Twilight Forest. It can be thrown and when it collides with a block or entity, will turn Water into Ice, Lava into Obsidian, and cover blocks with snow around a 3 block radius from its point of collision. It will damage all entities within its range by 1 () damage point and give them the Slowness III effect for 5 seconds. It will instantly freeze Yetis in its range into blocks of ice, at the cost of not dropping any of their usual drops.
Ice Bombs can be found as common loot within the Twilight Forest. They also drop from the Alpha Yeti at a large quantity of at least 6 copies.
