Well, ToonyMan wants me dead, so I'll probably be executed today. I'll full claim, accordingly.
My role name is This Setup Is Not Mechanically Solvable, Sorry.
I took Improvement -> Slow -> Overpowered -> Cascade -> Vulnerability -> Convolution -> Flux -> Meta, for the pain.
I started out with:
-(auto) Butterfly Effect (vulnerability, flux),
-(auto) Integrate (improvement, overpowered, convolution, meta),
-(night) Duplicate (flux, meta, slow, cascade, overpowered, improvement)
-(night) Accelerate (flux, meta, slow, cascade, overpowered, improvement)
And the Purple Chaos Emerald.
Butterfly Effect, back when it existed, chose a random player at the start of each Day, and until the next Day, if that player died, I would too.
Integrate would have, if my actions ever cumulatively targeted seven or more different spheres, cause me to gain a new ability based on those spheres.
Duplicate and Accelerate I've already claimed and can be verified.
On Night 1, I used Duplicate on Overpowered, because I thought it'd be a popular choice and it'd make a copy of Accelerate.
On Night 2, I used my Accelerate copy on Cascade, and my base Accelerate on Improvement, to make the widest splash possible and also make the original Duplicate Free in Imp's hands. I know Imp said it'd become Free anyways, but I don't know if that costs some kind of resource?
Currently, I have the Purple Chaos Emerald, a Ritual Knife, and (auto) Butterfly Integration (meta, flux, fruit-selling), which I gained Night 1 after losing both Butterfly Effect and Integrate.
Whenever a player dies, Butterfly Integration gains a random sphere that player had as part of their abilities. (If a sphere would be gained twice, the gain is cancelled.) If it ever reaches seven spheres, it transforms into a new form based on the spheres it gained.
It started out with meta and flux, then I was told it gained fruit-selling.
That's all I've got to claim. Any questions?
