Heimerdinger Build Guide (Mid)

Heimerdinger turns mid lane into a fortification project: H-28G turrets hold the wave and zone trades, Hextech Micro-Rockets punish anyone who walks up, and a CH-1 grenade stun into the turret nest is a kill.

Heimerdinger Changes

Patch 26.18

buffCurrent Patch

Heimerdinger's bugfix last patch ended up being a massive hit to his power, well above what we expected. So we're buffing him back up, partially reverting some of our previous nerfs. Because the double damage turret bugfix was significantly top lane skewed, we're looking to buff his performance in top lane most of all and fix a couple of minor mismatches that escaped his release.

Base Stats

  • Base Health Regeneration: 4.5 → 5.05
  • Base Damage: 28 / 36 / 44 / 52 / 60 → 30 / 38 / 46 / 54 / 62
  • Mana Cost: 65 / 85 / 105 / 125 / 145 → 60 / 75 / 90 / 105 / 120
  • Cooldown: 14 / 13 / 12 / 11 / 10s → 13 / 12 / 11 / 10 / 9s
  • Cast Range: 920 → 925

Patch 26.17

change

Heimerdinger is on the strong side, even after last patch’s nerfs. He’s got a meaningful bugfix this patch, so we wanted to call it out directly.

W - Hextech Micro-Rockets

  • Range Display: Now accurately displays the actual missile range.

R - UPGRADE!!!

  • Bug Fix: Fixed a bug where R-empowered turrets dealt double damage.

Patch 26.16

nerf

Heimerdinger is the single best-performing mid laner, and he's way up there in top lane, too. We expect him to do well for now, considering how rusty the average player is, and how strong his turrets are, but he's still outperforming our expectations. We want to make him more vulnerable early in his turret fortress and create a larger window without his pocket crowd control. For the rockets, they simply lack the early game counter-play required for a base damage this high.

Q - H-28G Evolution Turret

  • Base Attack Damage: 30 / 38 / 46 / 54 / 62 → 28 / 36 / 44 / 52 / 60

W - Hextech Micro-Rockets

  • Base Damage: 85 / 135 / 185 / 235 / 285 → 70 / 120 / 170 / 220 / 270

E - CH-1 Concussion Grenade

  • Cooldown: 13 / 12 / 11 / 10 / 9 → 14 / 13 / 12 / 11 / 10
