Okay so here's the idea If you have any of space guy's team things then this would come in use.
when a player says /sacrifice [life reciver here] then it would give up one of the player who said the sacrifice to the person who they gave it to along with this I would like a sacrifice request when the player says
/sacrifice request [request reciver here] then a pop up would say [the sender of the request] would like a life will you give them one?
the sacrifice request should be able to be sent once per 5 minutes so they couldn't spam request
do this and you get a
edit you can sacrifice yourself
