Be aware, it is not all sunshine and crystalline booty when cleansing the world of Hunger crystals. Not only will the player destroy many picks and hammer, but there is also a substantially increased food cost when standing near a Hunger crystal. The crystals all periodically drain a bit of the warmth out of the world; to the player, this translates as the food pool. If you are going shard hunting, make sure to bring extra food.
