Iron Fist

Iron Fist is a caestus found in GORN.

Details
The Iron Fist is a caestus that makes your hand completely iron and much stronger than usual. However, you cannot grab weapons with this equipped.

Tactics
The Iron Fist can easily break armor (especially leather) and is useful against bosses covered in armor, like the General.

However, this caestus is not very effective against Achilles' armor because it cannot break easily.
