Whenever a player dies he drops a strength item on the ground
Strength item can be crafted, or gained by killing players, consuming it for +1 strength
Each positive strength gives you +1 attack damage up to 5
Each negative strength gives you -1 attack damage up to -5
Whenever someone dies with -5 strength, they get banned
Revive book can be crafted to revive a player that got banned
