Ice Walls are naturally-occurring background Walls found in the Ice biome. They can be destroyed with the Hammer, but can't be picked up as an item.
主机版、 前代主机版、和 3DS版 Ice Walls cannot be crafted by the player. Therefore, they can never be placed or utilized in any other way by the player.
电脑版和 移动版 Ice Walls can be crafted from 冰雪块 at a 工作台 with Ecto Mist.
