From DragonMineZ Wiki
A stack form doesn't replace your current transformation: it stacks its multipliers on top of it. The clearest example is Kaioken: a Saiyan can be in base form or Super Saiyan and also be in Kaioken x2 at the same time, multiplying whatever form they are already in. The built-in stack form groups are kaioken (x2, x3, x4, x10, x20) and ultimate (StackForms.java).
