Heimerdinger periodically stocks a Turret Kit charge, up to a maximum of 3.
Up to 3 H-28G Evolution Turrets can be deployed at a time, with those deployed beyond the maximum destroying the oldest one.
Turrets deal 50% damage to turrets and inhibitors. They gain 50 bonus range against minions if nothing else is in range. If Heimerdinger is too far away, they deactivate after 8 seconds.

Heimerdinger deploys a H-28Q Apex Turret at the target location, which lasts for 8 seconds.

W
Active
Heimerdinger launches a wave of 5 rockets that converge upon the target location and fan beyond it up to a maximum range, with each one dealing magic damage to the first enemy it hits.
Every rocket hitting an enemy champion grants 20% beam charge to all H-28G Evolution Turrets and H-28Q Apex Turrets within 1000 range, up to a maximum of 100% beam charge when hitting 5 rockets on an enemy champion.
Enemies can be hit by multiple rockets, but receive less damage from ones beyond the first. Against minions, this lesser damage is increased by 200%.
UPGRADE!!! -
Active
Heimerdinger unleashes 4 waves of 5 rockets in quick succession that converge upon the target location.
Each rocket deals magic damage to the first enemy hit.
Enemies can be hit by multiple rockets.
Champions and monsters receive less damage from the second to fifth rockets that hit them, which is reduced by 50% for rockets beyond the fifth.
Minions instead always receive 100% of the initial damage from every single rocket.
E
Active
Heimerdinger hurls a grenade at the target location that detonates upon impact, dealing magic damage to nearby enemies and slowing them by 35% for 2 seconds.
If the grenade hits an enemy champion, all H-28G Evolution Turrets and H-28Q Apex Turrets within 1000 range of the impact gain 100% beam charge.
Enemies hit at the center of the grenade's impact are also stunned for 1.5 seconds. The grenade grants vision of the target location for 1.25 seconds.
UPGRADE!!! -
Active
Heimerdinger hurls a massive grenade at the target location that bounces a fixed distance 3 times in the cast direction.
The grenade explodes upon landing each time to deal magic damage to nearby enemies and slow them by 35% for 2 seconds.
Enemies hit at the center of the grenade's impact are additionally stunned for 1.5 seconds.
Enemy champions can only be damaged once per cast, but can be slowed and stunned multiple times if circumstances permit.
R
Toggle
Heimerdinger empowers his next basic ability for an additional effect, consuming the empowerment upon cast and placing UPGRADE!!! on full cooldown.
These empowered abilities have the same cooldowns as their basic forms, deal modified damage, and do not have a mana cost. UPGRADE!!! incurs its static cooldown on-cast, and can be toggled off to remove the empowerment and place the ability on its static cooldown.
UPGRADE!!! can be used while affected by cast-inhibiting crowd control.
2 summoned units on this kit. Hover underlined numbers for every level.

Up to 3. Starts with 0% beam charge. Recharge 20s. Deactivates after 8s if Heimerdinger is too far. 50% damage to turrets. Beam is ability damage.
R + Q · UPGRADE!!!
