Would test it out now but away from home right now. Here’s a pic, stolen from the Battleschool rewards thread:
Is it affected only by accelerators and supply stations? Or just supply stations? Or is it also affected by turrets?
Elite Bots probably don’t make it proc or anything even though they technically are buildables. I feel like this would be a good legendary for Kleese or really any builder character. Oscar is also good for this stuff, and especially Pendles.
