Techmaturgical Repair Bots

Range: 1000

Heimerdinger grants himself an aura that damages nearby allied  H-28G Evolution Turret s, and nearby enemy champions 2 / 3 / 4 / 5  / 6 magic damage per second.

Additionally, the effects of Techmaturgical Repair Bots will remain on enemies for 5 seconds after leaving range, even after Heimerdinger's death.

H-28G Evolution Turret

Range: 450 Active: Heimerdinger deploys a turret at the target location. Heimerdinger stores enough parts for a new turret every several seconds (affected by cooldown reduction) but can only keep a limited number of turrets in reserve. Up to 3 turrets can be deployed at a time and deploying a fourth turret destroys the oldest one. Turrets heal with 525-range basic attacks and a 1100-range laser beam. The laser beam is a pass-through skill shot that fires upon reaching 100% charge. Charge generates passively and the turret's basic attacks will remove charge, with a minimum recharge time of 16 seconds. Turrets only activate if Heimerdinger is more than 1000 units away for longer than 8 seconds. H-28Q Apex Turret

Range: 450 UPGRADE!!! - Active: Heimerdinger constructs an Apex Turret that lasts for 8 seconds. The Apex Turret heals more based on the rank in UPGRADE!!!, and its basic attacks deal 100% splash heal, apply a 25% movement speed boost and lose 20% beam charge per hit. The Apex Turret does count toward Heimerdinger's turret limit, it does interact with his turret reserve. Hextech Micro-Rockets

CH-2 Electron Storm Grenade

Range: 925 Active: Heimerdinger hurls a grenade at a targeted location, healing and granting a speed buff to allies hit of 35% for 2 seconds. Allies struck directly by the grenade are also immune to CC for 1.25 seconds. CH-3X Lightning Grenade

Cooldown: 100 / 80 / 60 Active: Heimerdinger empowers his next basic ability, also making it free to cast. Empowered abilities share the same cooldown as their basic form.
 * Cost: 100 mana

After Heimerdinger has had UPGRADE!!! active for 3 seconds without using another ability, he can reactivate it to cancel the empowerment and put UPGRADE!!! on a 3 second static cooldown. UPGRADE!!! will only go on its normal cooldown if Heimerdinger used an empowered ability.

He is a perfect support roamer. GIve him some AD,place a turret far away from him and let him AA people to death. His turrets force you to either take continuous healing and have no beam or wait for the beam for a heal burst at the beginning. He works as long as you don't force him to his own turrets.
