Elemental moves?

[Mickey Mouse]

Mechanically, alternate forms only alter your stats. You can say "I don't have access to lightning unless I'm in my alternate form" for RP purposes, but mechanically that's not actually how it works.

So yeah, it'd still cost the same as upgrading your Wall of Frost to have Lightning in a normal form.

So I just have to buy the upgrade for each move with them being restricted to the alternate form, and then can only need the lightning boost in actual text for RP purposes?

Let me see if I can say that better:

You have this move, "Wall of Frost" (for example) you wanna infuse with Lightning in Alternate Form A.

Alternate Form A costs 2000 OM. You purchase it.

In order to make Wall of Frost have cool sparky effects, you pay 300 OM to add in the "electric" effect.

Technically you can use that any time, but you only use it when in Alternate Form A. That's purely RP fodder and your choice, but you can do that.
