Looking to make a Constitution Obliteration Build. Sort of a one-trick pony, but that's fine.
Things I've found so far:
- Venom Domain grants Venomous Saliva, which allows Swift Action application of a CON poison to a weapon. This poison is non-magical poison.
- Venom Domain grants the Poison Spell earlier than any other capable caster (as early as level 5). This poison is a magical poison.
- Touch of Slime afflicts enemies with a lesser Green Slime, dealing 1d3 CON damage. This is a disease affliction.
- Purchased injury poisons (not ideal because they're expensive)
The above four sources stack with each other. If all of the first three are affecting the same target, that's 2d3+1 CON damage every turn. That's between 3 and 7 CON per round with an average of 5.
I still want to push the limit further. Without resorting to purchased poisons, is there any other source of CON damage (not CON penalties as they do not reduce CON past 1) available to a player? Keep it Paizo only.
