So in light of runes reforged, Lets do a make your own Rune thread
I mean why let Riot have all the fun. We can come up with our own borderline broken keystone runes. I bet we can come up with even better idea's then Riots team.
That being said i like many of the keystones so far, yes there are many really strong ones but you will have to give up a bunch of things for it as well
Anyway ill start with my own rune
Spell slinger (i know pretty lame name)
Here is what it does
Every spell cast and every spell that successfully hits an opponent reduces the cooldown of your other spells by a small amount ( 0.5 - 1 seconds or so) per opponent hit Every successive cast beyond the first costs 10 more mana
Not casting or hitting an opponent for more then X amount of time resets this effect and lets you start at normal mana cost again
So basically you get to spam really hard as a mage/caster but with ever increasing mana costs
Ok now it's your turn to create a new rune
