Seems to be sparratic, of course when I try to take a pic of it I can't seem to get it to happen =/. Might just be crazy lol
I'm pretty sure that's intended. I've been noticing that before this patch. The ball itself does damage (less than detonate) and then detonation does damage. So if you time right, then you can hit 2x total (not 1x ball and then 2x detonate). It's the same theory as Coated Bullets with #1 pistol. Bullet pierce does dmg and if you are at the right distance, the explosion also does dmg.
