Increases target's attack speed by 5/10/15/20/25% and Attack Damage by 7/14/21/28/35(+.X AP) for 20 seconds. 12 second cd
*the cooldown and buff time are roundabout numbers
Micro-Rockets: remains the same
Grenade: Damage/ratios remain the same(minus the ability to damage buildings), Blind duration kept at static 1.5 seconds. Stun should be increased to 2.5 or 3 seconds as its the slowest skill shot in the game and i think its effect should reflect that.
Mini Turret: Create a turret at target location. Turret does 25/50/75(+0.x AP) splash damage to enemies. Lasts 20 seconds. 20 second cooldown. Can only build 1...
*You can tell the turret what to target similar to the way you control tibbers and shaco's illusion.
Also the duration and cd are no coincidence they are meant to encourage you to get cd reduction so you can move you turret again before its duration is up.
I like the idea that Riot is trying to make Heim a pusher and i think giving a support buff would be a good idea to give him more value than solely a pusher/defender...
