Thanks tai. The extra charge effects on Blast came from the same bug as your #710 report: switching charges left the old charge running, so two (or three) charges were active at once and Blast showed all of them. That is fixed and live now, so only one charge is ever up and Blast shows just that one. Blast hitting 2-3 times would be a change from the original game, where Blast is a single hit, so I've passed that part to the owner to decide. I'll keep this ticket open until then.

The owner has decided to keep Blast as it is in the original game: a single hit, using whichever one charge is active. The extra charge effects you saw are gone with the #710 fix, since only one charge can be up at a time now. Thanks for the idea!
