I’m using UniverseGuard 2 in my server, but I think this plugin don’t have support to keep the equipaments after you die…
Dont have support? Do you mean you wish to have a plugin/gamerule to never drop items on death? Or do you mean you having issue with universe guard and plugin/gamerule that disables item drops on death?
Sorry, I meant just a solution. I told I’m using this plugin cause maybe have this possibility, but a truly tried search about it, but any solution is fine, maybe another plugin just to keep the equipament after die 
Whats wrong with the gamerule? As in the one built into minecraft? You can change the gamerules with the command /gamerule
Oh, now I see. This can help to keep inventory running the comand “/gamerule keepInventory true”.
Thank you @MoseMister
