Heimerdinger in League Classic
Champion Bio
League's brainiest champ, Heimerdinger, waddled onto the rift shortly before the game's full release and promptly showcased just how much power goes into brainpower. One of the game's most oppressive laners, Heimer would hang out behind his turrets while his inventions turned his opponents into the same "undesirable experiments" he'd lecture about!
What Changed in Classic
- The abilities may look similar but are very different - UPGRADE!!! (R) is a buff that lasts a set time not a single ability - H-28G Evolution Turrets (Q) are active globally but die when Heimerdinger does
