Periodic Rune Spawn System?

[Fundo!]

Anybody know how i can achieve this?, spawns a rune every x game seconds, and checks if a rune is alrdy in the spot then skips the trigger then waits until the rune is removed to trigger another random rune to be spawned. The trigger i have seems to be buggy Spawns 1 randomly then dusnt fire again. thanks in advance

maybe you post your trigger, which doesnt wokr?

I would recommand an area, in which you create the rune-items, then check if there are any items of this kind in this area. If there are -> return, if not, create a new rune.
