Official Move Approval IV

[Undyne]

300 for the basic whip, 300 for the debuffing part and 300 because Sabrina can shorten the whip's max range (last sentence before the fluff). I imagined that it would be variable enough to be priced extra for that?

You wouldn't need to pay for the third use as that's just changing the way you hold the whip. I'd compare it to having a Dual Swords move and only using one sword or grasping a large sword with one hand versus with two. The whip isn't exactly changing size, you're just holding it in a way that makes it not entirely useless at close range.

Hmm, I figured that it would be variable enough (and "circumventing" a normal whip's limitations) to justify a price increment. Not that I'm complaining if you say that 600 is fine though!
