Lua UMP - use only if...

[OTcreator]

Hi,
I came up with this idea.
Since, the players on the server are not many, I initially removed the ability to use UMP completely.
I stayed with the GREAT maximum potions.


I came up with the idea to give the possibility to use UMP, but only if the player:

1.) He has no PZ.
2.) He doesn't have a skull.
3.) Is not attacked by a player / has not attacked a player.


I know it would be possible to do something like this, just which option would be best?
If we give only when someone attacks him then after the hit, he can use it.
If we give a time limit on storage, that's not exactly a good idea either.

Does anyone see something better here?
The main point is that with PVP and UMP with a small number of players, it will be hard to, for example, such an ED/MS on utam to kill in 2/3 os.
That's why the idea came out to give the possibility to use it only during the expo.
If there is a duel , it can not be used.


Does anyone know how to solve this in the best possible way?
