Lab Report: Reinventing the revered inventor
The first major discovery proved the mass previously known as Heimerdinger’s brain is actually hair. After what must have been days of cutting, styling and shaping, Heimerdinger returned to his lab to experiment with his new do.
With his hair density significantly reduced, Heimer implemented a long languishing invention: the D.I.N.G.R., a neural-engaged robotic arm. This schematic shows the arm of the D.I.N.G.R. lying in wait for Heimerdinger's supercharged grey matter to raise the apparatus and launch a bevy of rockets and grenades at the enemies of science and progress.
But Heimer can't call anything an upgrade if his turrets aren't included. Whether sporting original 'Dinger [ | , Piltover Customs [ | , Alien Invader [ | or entering the Blast Zone [ | , there'll be no mistaking these death devices for ye olde pitching machines.
Heimerdinger visual update out of the lab!

A good long tinker with the 'Dinger yielded some epic upgrades to his turrets, rockets, and grenades. Now the updated Heimerdinger struts out of the lab and onto the Rift. Because the diminutive inventor isn't all explosions, a spiffy new do adds some style to the dangerous substances.
