How to cleanly remove klepto rng.

So there are only two elements to the klepto rune. 5 gold on each prock and a item every now and then. The problem is the item every now and then being too differnt. Mana potions are useless and gold bags can break the game. So how does someone go about solving this?

Well for starters you could completely remove the randomness and make it apply like bards passive. Where every 3 attacks give a potion and every 10 give a item that both players can see.

Or if you wanted too you could switch the entire item pool towards dueling and remove gold bags. Of course to supliment this you could make each prock give 7 gold. The items are actually the kind of rng already in league. With tryndamere you can see how much rng he is working with as such its fine rng. Since you can see what your opponent gets before he uses it, the item is seeable rng.
