Stop_PvP

The mod allows for punishing those who flee from PvP. When players engage in combat, a PvP mode is activated, disabling the ability to teleport. If you leave the server while PvP is active, you'll be killed, along with your items.

To enable PvP mode, enter the command "/pvp_tag (the nickname of the player you want to enable PvP mode for)"

And to set the PvP duration, enter "/pvp_time (duration in seconds)"
