  1. First buy

    1. Doran's Ring
    2. Health Potion, 2 of them

    Every turret costs 70 at rank one, and the second slot only arrives at rank three; the regen decides how often they get rebuilt.

    Alternative start:
    1. Boots of Speed
    2. Health Potion, 4 of them

    With 14 base armor, Heimerdinger cannot trade through a poke rotation, so he buys the speed to skip it.

    Alternative start:
    1. Null-Magic Mantle
    2. Health Potion, 2 of them

    Turrets hold the wave; magic resist holds Heimerdinger, and against a mage that is worth 400 gold.

Coming from current LeagueR is not 'empower my next spell': it is a duration buff upgrading everything at once, so it should be cast before a fight while rotating W and E repeatedly; W also cannot miss.
Remembering Heimerdinger in 2013Turret count and quality are gated by Q rank in a way no historical Heimerdinger did, and the health-regen passive helping structures means he defends towers rather than pushing.

History & Notes

Released 2009-10-10, one of the original forty champions. Classic ships the pre-rework kit, frozen at patch 3.13.24. The modern game plays a different champion, compared under “Vs. modern”. Riot's next 3 balance steps after the freeze are listed below.

The freeze date and this champion disagree. Classic ships CH-1 Concussion GrenadeCH-1 Concussion GrenadeEActive: Heimerdinger tosses a grenade at a location, dealing magic damage to enemy units and blinding them. Enemies hit by the center are stunned for 1.5 seconds., the version that blinds the surrounding area and stuns a direct hit for 1.5 seconds, while patch 3.13.24 itself had already replaced it with CH-2 Electron Storm Grenade. The kit here is older than the patch the mode is frozen on, and the passive still repairing allied structures dates from the same side of that line. The turret ladder belongs to neither side of it: the champion before and after V3.13 both fixed turret charges at 1/1/2/2/3 by rank and gave the turret a laser, where Classic gives 1/1/2/2/2 charges, no laser at all, and hangs the shred, the second turret, the bonus health and the area damage off the ranks instead. The prices moved too: a turret costs 70 to 110 mana where Season 3 charged a flat 20, and UPGRADE!!!UPGRADE!!!RPassive: Heimerdinger gains bonus cooldown reduction. Active: Heimerdinger empowers all abilities and turrets for the next 10 seconds. * Evolution Turrets: All turrets are healed for 100% of their maximum health and each attack slow targets hit. * Hextech Micro-Rockets: Fire 5 rockets instead of 3. * CH-1 Concussion Grenade: Travels 33% faster. runs 120/105/90 seconds against 100/85/70.

The live game then spent the steps listed below building onto exactly the beam Classic left out, tuning its charge rate, its ratio and its damage. None of that reaches this turret, which has no beam at all and attacks for 30/38/46/54/62. The two lines cross once by accident: the same patch that retuned the beam raised his base armor to 14 from 10, and 14 is what Classic lists.
