This wont surprise you but one of my favorite genres is when you take an anaemic girl and give her 300 big macs. naturally my first build is going to be vepar gluttony. it seems viable enough bc you can make it like the old bulbasaur builds where you put down leech seed and toxic (which does more damage each turn) and leech seed would take 100% of the damage of toxic as health. It was fucking busted. Anyways if health on kill is added my gameboy boomerism is coming back. Overall. we have almost the exact same tastes bro.

I don't have it fully figured out, but here's what I do have!

Wrath - Juggernaut and Rancor both focus on muscle growth. They might target different areas, but they already do that for the imps (Vepar gets stronger legs for instance) so we'll see.

Lust - Broodmother = pregnancy, Succubus = breast expansion.

Sloth - both Creeping Death and Vicarious Dreamer focus on butt growth.

Gluttony - Gourmand features weight gain, and the Everstarved features belly stuffing with some vore themes.

After these four I'm less decided. The next three I'm saving until I feel the first four are in a good spot thematically and mechanically so I don't make them redundant. Buuuut I do have a few ideas.

Greed - all I have right now is that Hustler will wear finer clothes, and Gilded will wear tons of jewelry that acts as armor.

Pride - Egotist will feature some mini-giantess/height growth, not sure about Braggart. That one could be hourglass maybe.

Envy - I plan on making it so Imitator can mimic any of the other sin subclasses, but I don't know for sure how difficult that would be to do. Haven't decided with Covetor.

But again, the last three aren't a priority until I'm in a good place with the first four.
