It adds the chance of dropping that players head, skin and all, when they are killed. I know you are trying to discourage PvP, but this would be a really cool feature. "Avoid humiliation by not engaging in combat". Just thought it would be a cool addition. Bukkit Plugin Link
When you ask for a plugin, weirdly, I already know this one So this plugin doesn't worth it on SKCraft, this is just against most of the rules to PvP, and if you do, what will you do with the head of the buddy ? On a PvP server, it could show how many people you killed, but on a regular server, it just looks like a bad idea!
