I’ve probably got some more stuff to say, but lets keep this one simple and short, because of what I just saw with how single-explisions work:
Increase mana gained from explosions from 50% to 51%. (you don’t even have to update the tooltip, you can just change the back end)
It should not be possible to explode a single gem and gain zero mana from it, but that is the current state with exploders at 50% - mana gained from exploding a single gem of a color is rounded down. Kinda kills all low-yield explosions. Mass exploders can rely on cascades, but I’m not sure why these were swept up in the nerf.
