I'm playing a gnoll ifrit mosquito witch in outlaws of alkenstar (both geniekin and gnoll are recommended ancestries). I pumped strength and my stats are 16str, 14dex, 12con, 8wis, 18int, 10cha. I plan on going into the hair feats, and taking wrestler archetype so I can do some cool stuff with the hair.
I recognize its pretty suboptimal but its cool so I went for it. The biggest issue is how fragile the character is.
I've also tried to collect abilities that grant me fire damage, so I can trigger elemental betrayal as much as possible when I get it at level 2. The lava spike attack from the ifrit heritage is good for it, and once I hit level 3 I can learn the flame wisp spell which will let the lava spikes trigger elemental betrayal twice (the wisp is a separate source of damage). Alchemist's fire also synergizes well because the persistent damage triggers the bonus as well.
I'm a bit bummed out that the flame wisp familiar I took buffs basically none of the damage outside of fire spells though, but its still pretty thematic.
