Hey RiotScruffy, we were talking about an Ammo mechanic recently, right?

You remember what we discussed here, right? Well I think I've got a V1.0 rolled out for a concept that uses it.

Check out the following: http://boards.na.leagueoflegends.com/en/c/fancreations/yq1UxMZq-yousoconcept-terminus-the-war-machine

Brief Summary

Terminus does not use mana; instead, he uses a new resource, Ammo, every time he attacks or uses an ability.

Passive: As long as you have Ammo, your attacks deal bonus physical damage.

Q: (First Cast) Fire an orb that damages enemies it passes through. (Second Cast) Fire a bolt that damages the first enemy it hits. If you shoot the orb with the bolt, an explosion is released that does strong damage.

W: Fire a shockwave in target direction, damaging and knocking back enemies. Enemies too close to you are briefly stunned.

E: Shield yourself and replenish your Ammo. Long cooldown.

R: (Toggle) Your attacks and offensive spell-casts spend more Ammo to fire missiles in a cone in front of you, damaging enemies they hit.

You'll need to check out the above link for more details. Don't criticize based only on what you read here.
