Lootpid

Lootpid: This new cave mob is found where ever you can find a chest underground and near lava lakes. This mob has three forms, one with and without it's crystalized shell and lastly can have a chest as a shell.

When equipped with it's shell it will first turn itself into a ball and rolls at full speed towards the player. This attack give player a heavy knockback and the mob with it's shell has a lot of knockback resistance. killing it will drop crystal shell shards which can be applied to a shield using a smithing table turning it into a spiked shield which will not only block damage but also hurt the mobs when they attack you and can also be tipped with potion effects(only lasts one time).

Without it's shell it is mostly defenceless and attacks like any other enemy. But if they could find a chest nearby they would run for it and crawl inside it,turing into a chest lootpid and using chests as a shield.

This type of lootpid acts more like an mimic and will replace some of the chests in underground structures. When nearby won't do anything but if you try to open them they would show their true form and has a chance to block the incoming attacks by a player(Easy: 25%, Normal: 40%, Hard: 65%). Killing it will drop the loot that was present in the chests and the chest itself.

Common drops: All the three will drop lootpid pincer which can be used to brew a potion of stability that reduces knockback.
