I've been able to implement a new feature that lets people now set a price that is taken out of the the players balance. This can be any amount you set in the config. If the player does not have the amount you are able to set a penalty for not having the cost. This will send a message to the player and apply a potion effect to the player that they are unable to remove. It can be any potion effect you want. You are also able to determine how long the potion effect will last.
To apply this to a specific group or user just simply give them the permission omegadeath.deathprice
Bug Fix:
I noticed there was a small bug with the reload command, with the permission so that's all been fixed now.
