Skeleton Commando

The Skeleton Commando is an enemy that spawns in the Dungeon in Hardmode and fires Rockets at the Player. They are immune to the Poisoned and Venom debuffs. Just like the Blue Armored Bones they only spawn in dungeon with a Brick Wall. Skeleton Commando is very dangerous as it can deal lots of damage if you are going ranged or mage. The best way to fight it is to use a fast weapon to cancel his attacks, since they require a brief time to fire. If they are swarming you with other hardmode dungeon enemies, esp. the Paladin, you will either die or take damage to a crucial amount (unless you are using the mage set Spectre Armor, which is insanely great in the dungeon). Even during late-hardmode, they can be a dangerous enemy to fight since they usually have the protection of Blue Armored Bones and not get focused down.
