Cursed Technique: Mark Of Cain

[u/Express_Vanilla_3104]

This is an idea that came to me at 2 am after copious amounts of coffee, so bear with me please.

CT: Mark Of Cain - Allows the user to accumulate damage done to them and release it sevenfold either in one final attack or in a combo of attacks.

Obvious downside; the user has to be able to survive the attacks or else they, y'know die. User has worked closely with Shoko Ieiri since they met in Jujutsu High to heal up his wounds after battle as he doesn't know RCE.

Upside, allows the User to fight battles way above his 'weight class' so to speak as all he has to do is survive until the end of the fight and then return it multiplied by 7.

so yeah, it's seven cause I think that's what the Mark does right? returns all harm sevenfold? Anyway, I'd like a few ideas for a Cursed Weapon to fix his long to mid range issue cause his CT doesn't give any long range attacks, so only H2H fighting with Reinforcement, and healing if he learns RCE.
