tease out the impurities
You can use it to extend combos off 124 and 44 in the corner; the recovery is obnoxiously long so converting afterwards isn't easy. Against male hitboxes, you can 124~BF3 AMP for a little extra damage if you have the meter; I think F43~BF3 AMP also works for a little more damage than just F43~DB4 or something. It's not worthless but not great either.I don't get what BF3 is for... is it an antiair? when should I use it?
