When Safely push the wave and poke the enemy in lane

1. QTurret 1→
2. QTurret 2→
3. WRockets

Tip Spread Q turrets behind minions or along brush edges so they are not cleared together. Each W rocket that hits a champion grants nearby turrets 20% beam charge, so converging all five aim points on one target prepares beams quickly. Do not chase outside turret range; make the enemy step back into the charged zone.

When With turrets already down, land a stun and unload burst

1. QPre-place→
2. ECenter stun→
3. WRockets→
4. Auto

Tip Set Q turrets where the enemy will enter, then land the center of E's grenade on the champion for the stun. A champion hit instantly fills nearby turret beam charge, so overlap W rockets and a basic attack during the stun to trigger the beams together.

When Maximize burst on a secured kill or in a teamfight

1. QBasic turrets→
2. RUpgrade→
3. QApex turret→
4. EStun→
5. WRockets

Tip Pre-place a normal Q turret, then cast R-Q to deploy the 10-second Apex Turret. E stuns for 1.25 seconds only in its center, and any champion hit fully charges nearby turrets. Land the center stun inside Apex Turret range, then overlap W so the charged beam is not wasted.

When Catch a fleeing target or land a stun from an unexpected angle

1. Flash→
2. ECenter stun→
3. WRockets→
4. Auto

Tip Flash toward an area where Heimerdinger's turrets are already set, then surprise the target with E's center stun. The hit instantly readies turret beams, so follow with W at once; flashing away from Heimerdinger's turret setup loses much of the combo's extra damage.
