Spreading out Hextech Micro-Rockets leads to more reliable damage and more efficiency against multiple targets, but focusing it creates the biggest impact.
The success of Electron Storm Grenade is very important to Heimerdinger's survival. The slow and stun both are capable of keeping enemies in place long enough to punish them, but it is also the first line of defense against a surprise attack.
Turret placement can be a deciding factor in a battle. Against most enemies turrets are best when they can support each other, but if the enemy has a lot of area of effect damage your turrets can be destroyed quickly. Placing turrets in brush can lead to a surprise attack in your favor.
Use Moonfall and Lunar Rush to stay on targets and activate Moonsilver Blade for extra damage.
Consider when to cast Lunar Rush without Moonlight and when to wait for another Crescent Strike.
Landing Crescent Strike is critically important, but don't be afraid to miss. The cooldown is short and the mana cost is low.
