My apologies if this was already answered, but is it intended that the Ki cost of Ki weapons increase anytime you reforge them? I know it took me a lot of reforges to get Transcended on a Hellzone Grenade and then the Ki cost was insanely high. Also, the Dirty Fireworks seems to have bugged damage. It'll do around 110 damage after the explosion (as listed on the wiki), but the weapon itself is listed at like 1 damage, so a prefix that lowers damage will set the damage to 0. Once at 0, it's no longer treated as a weapon and can't be reforged.
