You are telling me that you changed an aspect of your character sheet after it was approved and play commenced, without DM permission, in direct violation of the rules agreed to in the original post. This is not encouraging. 

I would rather this be a lesson rather than an example this early in the one-shot, so for all parties present: 

This is not an acceptable route to take. If I see anyone making changes without approval past this point, it means removal from the RP. In a way, I am glad we're getting this out in the open early. It should save trouble down the road.
