Crystal Crushing
"Times up adventurers. Next opponent is powerful but if you can figure out its trick you'll prevail easily. Also bladed weapons are useless, you want something with a bit of a....punch." Says the dagger ghoul as the doors open and the group re enters the arena to the roar of a skeletal, mutant, or ghostly crowd.
"Welcome ladies and ghouls to round two of our monstrous showdown between our champions and the menacing adventurers. In our second round we have an accidental abomination of magic and necromancy! We all know and love her! I introduce Professor Crystul of the royal research foundation!!!!" Shout Em Cee into his mic as the doors open on the far side of the arena and the opponent stomps into the sand.
