Ice Shard

Ice Shards are a somewhat common drop by most Icengard mobs. It is one of the four items needed in order to craft the Frost Staff. It does have several solitary uses, which will make it able to be a plain item on it's own if there are some left over after crafting.

Uses
When right-clicked, it will spawn an Ice block. While mining Snow, Snow Blocks, Ice, or Tundra trees, it will speed up the mining process by 55% and have Silk Touch effects.
