Rune modification idea

All current rune are refunded in IP (The value they're worth CURRENTLY)

New rune cost around ~4000 IP, But you can only have 3 Runes at once now (Around ~12000 IP a full page) You can find and craft rune in Hextech Chest, they can be crafted/decrafted with/for Blue Essence.

Rune page still buy-able, price halved though. You can now at any summoners level put 3 Runes per rune Page, each rune must be unique (You cannot put three or two time the same rune, you have to chose 3 different rune)

List of runes : Rune of Omnivamp : You heal for 5% of the damage you deal (33% effectiveness for AOE)

**Rune of Initiation : **You gain 25 Move speed outside of combat.

Rune of Bloodlust : You gain 15% Attack speed for 3 second after landing a critcal strike (non-cumulative)
