[Wario]

Hold up, does this need Debuff at all?

Wario Waft (T1 Super Attack) - Area Attack, Debuff
Wario releases the mother of all farts, forming small mushroom cloud of methane. Everyone with any orifices in a spherical area of 12 feet within Wario is stunned for 4 seconds (unless you're underground or something). Separately, for every second you are within the cloud, you take some choking damage. The cloud lasts for 30 seconds. Such a massive gas cloud takes quite a bit of energy to generate, and Wario will find that he only has a limited amount of Stomach Power (SP) to repeat it in a fight.

Thinking about it, not really... No. You don't need debuff for "continuously damage all people within this area"-type things. That said, "choking" damage does sound somewhat debilitating - which is probably why I didn't question you adding the proficiency at the time I approved it (at least, I think I approved it - or at least looked at it in approval/your join app).

I believe this actually would need debuff, bolded part from the proficiency below:

Debuff Proficiency – 1000 OM (Example move)
Allows you to create moves which have a lingering or channelled detrimental effect against opponents. For example, an ice beam which slows or freezes enemies, or a flashbang grenade that blinds and deafens your opponents.

So taking that into consideration, if I clarify that people who are not in the area don't take damage (therefore it's not lingering), I won't need Debuff? Considering it's a "change the environment" thing?
