LoL Champion Build Guides: Heimerdinger

Heimerdinger constructs a turret at the target location. Heimerdinger stores the parts for a new turret every 20 seconds and can keep 3 in reserve. The storage time is affected by cooldown reduction.

Turrets feature a short-ranged basic attack which deals 6 / 9 / 12 / 15 / 18 (+35% of ability power) magic damage and a long-ranged laser beam which deals 40 / 60 / 80 / 100 / 120 (+55% of ability power) magic damage in a line. The laser beam is a piercing linear skillshot that fires upon reaching 100% charge. The passive recharge time of the beam is 16 seconds (not affected by cooldown reduction), but this is lowered whenever the turret attacks an enemy as its basic attacks restore 1 / 2 / 3 / 4 / 5 % of the beam's charge. Nearby turrets gain 20% charge for each Hextech Micro-Rocket (W) that hits a champion and 100% charge if CH-1 Electron Storm Grenade (E) hits a champion (same bonuses apply to ult-empowered W and E casts). Turrets go offline if Heimerdinger is more than 1000 units away. Heimerdinger can have up to 3 turrets constructed at a time.

H-28G Evolution Turret Stats:
Health: 150 (+25 per champion level)(+5% of ability power from levels 1-8, after which the ratio goes up by 3.5% per level up to 40% of ability power at level 18)

Heimerdinger unleashes a barrage of 5 rockets that converge on the target location and fan beyond it up to a maximum range, each rocket dealing 50 / 80 / 110 / 140 / 170 (+45% of ability power) magic damage to the first enemy it hits.

Enemy champions and neutral monsters that are hit by more than one rocket take 20% magic damage for each rocket beyond the first, up to a maximum of 90 / 144 / 198 / 252 / 306 (+81% of ability power). Enemy minions take 30 / 48 / 66 / 84 / 102 (+45% of ability power) damage from each rocket.

Each rocket that hits an enemy champion grants 20% beam charge to all turrets within 1000 range of the damage (max 100% if all five rockets hit).

Heimerdinger hurls a grenade at a targeted location, dealing 60 / 100 / 140 / 180 / 220 (+60% of ability power) magic damage and slowing enemies hit by 35% for 2 seconds. Enemies struck directly by the grenade are also stunned for 1.5 seconds.

If the grenade hits a champion, all turrets within 1000 range of the damage gain 100% beam charge.

Heimerdinger empowers his next basic ability, also making it free to cast. Empowered abilities share the same cooldown as their basic form. Heimerdinger can activate UPGRADE!!! again after 3 seconds of activating it to cancel its effects. Canceling UPGRADE!!! puts it on a 3 second static cooldown. UPGRADE!!! will only go on cooldown if Heimerdinger used an empowered ability.

Places a Turret that deals 70 / 90 / 110 (+35% of ability power) magic damage with its cannon and 100 / 140 / 180 (+70% of ability power) magic damage with its beam for 8 seconds. Each time this turret attacks, the beam is recharged for 20%.

Fires 4 waves that deal 135 / 180 / 225 (+45% of ability power) magic damage each. Champions and monsters hit by multiple rockets take reduced damage (max 503 / 697.5 / 892 (+183% of ability power)).

Each rocket that hits an enemy champion grants 20% beam charge to all turrets within 1000 range of the damage (max 100% if all five rockets hit).

Throws a grenade that discharges three times, dealing 100 / 200 / 300 (+60% of ability power) magic damage and exploding in a larger area each time. Enemies hit are slowed by 80%.

If the grenade hits a champion, all turrets within 1000 range of the damage gain 100% beam charge.
