I know obviously the burst frog... but apart from that what is the best unit to level up the BB limit? I have been using Burny, Mossy, Squirty etc...on elemental damage BB, because I figure they would keep zel cost down instead of levelling them up and making it more expensive, while also increasing the BB experiece, but is the BB experience relative to the level experience? Will I get a better result using other elemental damage units like Witch Liza or the low level units instead?
