RTFM
Okay, there are a couple points to clarify for how the arena works.
Cinder, alright, given that you were out of combat, the ogre didn't really do that. It's fine. Actually it's not entirely clear that you were out of combat, it sounded like you were waiting for an opportunity to jump in. Because with this arena, you're either in or out. No starting out and tagging in. It's not WWF. It's just magical like that. So you guys need to pipe up and say 'in' or 'out' before the next combat gets underway.
Second thing. You know how the Fightmaster said "the victor may choose only one"? He meant it. Renwick tries to grab the staff but gets a bad shock since he clearly wasn't the victor of anything. Then Marivhon grabs the glove, and both the staff and the bolts disappear. Make sure you all read that:
Marivhon takes the glove, and the staff and bolts disappear. They ain't invisible, they're gone. One prize per combat.HPs: Let's just say Dave FoO puts a Cure Lt on Marivhon and a Cure Lt on Brogg and everyone's up to full.
Okay, Marivhon picks up the nunchuks from statue VII and takes them over to the Fightmaster. Again, he asks everyone who will fight to step into the arena, and everyone else to leave. In or out. You guys see another gate open and a variable number of ninjas swilling around in the gate.
