Heimerdinger is good at zoning due to his turrets, but is an even better burst mage. Play patiently, hit your spikes, and then destroy your opponents! 

  • Level 1 - Take Q - H-28 Evolution Turret, so you can begin zoning and poking the enemy.
  • Level 2 - Take E - CH2 Electron Storm Grenade, for poke damage at range and area damage for farming.
  • First Back - A Lost Chapter starts your path to Liandry's and offers some much-needed mana early on.

Tips & Tricks

  • Your turrets load over time, and once loaded they fire a laser beam that inflicts heavy damage.
  • Hitting an enemy with Q then E instantly recharges your turrets. In addition, they'll focus on that enemy first.
  • Attacking an enemy with an auto marks them, so that your turrets target them first. Remember to use an auto before Zhonya's, so that all turrets focus down that target! 
  • Use Zhonya's once your target is within turret range, and let them do the hard work.
  • Your rockets disperse more or less depending on your cursor position.
