League of Legends Reforged Rune: Prototype: Omnistone

Periodically grants a single use of another random keystone.

5-3 second cooldown between using a keystone and gaining the next (9-7 seconds for ranged users). Will not give the player Press the Attack or Conqueror as their first rune.

After 40 seconds of not using a given keystone, Omnistone will re-roll when you exit champion combat. Aftershock is only available to champions who have learned a basic spell that can trigger it. Predator is only available to champions who have already purchased boots.
