The obsidian skeleton.
Basically an epic skeleton thats immune to lava, bows and any form of drowning or suffocation.
He has 45 HP
Can only be injured by a diamond sword witch does low damage.
Cannot be Crticaled. Can nont be knocked back.
His room is obsidian and lava.
The door locks behind you and water doesnt work in his rooms.
He has 2 forms. The first he uses an obsidian bow which deals 3 hearts of damage per hit and fires 1 time every 3 seconds.
His second form has a diamond sword and charges at you and attempts to knock you into lava etc.
This form happens at 25 HP left.
I personally think this would be cool
