Playing as Heimerdinger

Tips to maximize your impact

  1. Plant your turrets and stay close

    Place your turrets with H-28 G Evolution Turret (Q) where you want to fight, then stay close: if you move too far away, they deactivate after 8 seconds.

  2. Aim the center of your grenade

    Aim the center of CH-2 Electron Storm Grenade (E) at your target: only enemies in the center are stunned, and hitting a champion fully charges your nearby turrets.

  3. R then W for the kill

    To kill a target, cast UPGRADE!!! (R) then Hextech Micro-Rockets (W): you fire 4 waves of rockets instead of one.

  4. Giant turret for objectives

    For a teamfight or an objective, cast UPGRADE!!! (R) then H-28 G Evolution Turret (Q): the turret lasts 8 seconds, slows, deals area damage and is immune to CC.

Playing against Yuumi

How to counter and exploit weaknesses

  1. Stay behind your minions

    Keep minions between you and her: Prowling Projectile (Q) stops on the first enemy hit, and once accelerated, it slows hard.

  2. CC her as soon as she detaches

    If you have CC, save it for the moment she detaches: once immobilized, she can't recast You and Me! (W) for a while.

  3. Focus the champion carrying her

    Focus the champion carrying Yuumi: attached with You and Me! (W), she can only be targeted by towers, and without them she's left exposed.

  4. Cut her healing

    If you have Grievous Wounds, apply it to the champion carrying her: they receive her healing, including from Final Chapter (R).
