The limitations you propose for "Feeling Bombastic" sound reasonable, as do the changes to your other abilities/skills. Being able to make 3 bombs a day is probably a safe bet, and having them expire every 24 hours would keep them from accumulating. Basically, feel free to make whatever changes you like, just do so with the fact that you need to bring the overall power level down a bit in mind. When you're done post here and I'll review your abilities again, and we'll go from there.

Remember to provide more info on what specific changes "Mutagen Mania" makes to the user, and add in the materials your weapons are made from.
