Tri Towers Challenge

The game is really coming together.  In testing i'm finally climbing the tower and not constantly resetting.

Various tweaks to the defend the iron golem  and iron golem 2 rooms.

the iron golem boss now has creepers spawning with him. And yes you can kill him with them instead of fighting.. i'm debating if i like that.. It seems a bit easy for a boss mob if you do but its at least interesting. So I dunno. even nerfed he hits like a truck

Added assistance mobs to the ravager and the evoker as well. the ravager might have the same problem as the iron golem where it attacks the assistance mobs so .... i might change that.

Added a item recall npc. if you die in the tower and have the emerald blocks to burn you can summon your items back to you (and any other loot in the towers on the floor, not yet decayed)

Tweaked the level based loot so you can get most anything you might need to make potions or an enchantment table without leaving the tower. I also added iron blocks in the random junk loot table that you get all the way up the tower (they are kinda rare) so you dont have to redo lower levels just for iron to make anvils.

Also balanced the undead regen to not be so broken. might need another nerf. the same goes with speed buff mobs sometimes get. either way its becoming much more bug free and balanced.
