Item Unique

[Ify90]

So i got this 4 items , charged up type cuz i got no other items there
I get my mind blown trying to make a trigger that allow you to have only one of them at all time in the hero . The item must be not repeatable and the others must not be able to be picked up .
If the hero tries to pick one of the 4 items while having any one of those 4 to drop the trying to pick item
