Guide to Synergizing Karthus and Heimerdinger

Tips for Playing as Karthus with Heimerdinger

Lay Waste is very strong at farming minions and harassing enemy champions.

Ask your allies to help point out when you should use Requiem to get kills in different lanes.

Advice to Understand How Heimerdinger Will Play

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.
