Need help determining this character's power cost

[Kakashi Hatake]

Hello! Welcome to the Omniverse!

So, as for your question...this sort of thing is a bit iffy. You COULD make this work with a series of powers and moves if you'd like, though there'd be some caveats. The largest caveat is that you'd need a move for each thing you'd want to accomplish with Good Luck/Bad Luck. The dice-roll could then be something you'd use out of character to determine which moves are used when if you'd like, though I'm not 100% sure that would fly as it's a bit meta.

In terms on inflicting bad luck on an opponent you could have a move that utilizes Debuff Profifiency but you'd need to explicitly state how you'd want it to work as just saying 'bad luck' is too broad and could encompass many effects. Maybe you'd want to lower their TEC by a bit for a duration to make them more apt to miss, etc. Something like that would be fine. Or maybe you could have it lower their speed by making them more clumsy. As for debuffing yourself, I don't think you'd need to buy anything. Just RP him tripping or something.

As for Good Luck, you could surely make a buff move that boosts TEC (I'm just assuming that's what you're implying with luck) but it would ONLY work on other players. We don't allow self-buffs unless you wanted to make it a transformation/power-up and spend SP to boost your stats. If you wanted to just start your character with 5 TEC or something and RP it as him being very lucky with his attacks, that'd be cool though. You could also considering having an alternate form that maybe has a larger stress on the TEC stat.

So short answer, it'd depend on what you exactly mean by luck. Various effects would require additional proficiencies/powers but I'd say you would definitely need Buff and Debuff to just inflict clumsiness or aptitude on others. I'd personally just play a high TEC character with Buff and Debuff profiencies and work on a few moves that revolve around 'luck'. Like a punch that incapacitates by hitting JUST the right spot or a dodge that is timed perfectly. Definitely doable and a fun concept. I hope that answers your question!
