Surf through recipes to poison recipes, then select quick trivial list. Examine recipes for ingredients that can be purchased and are above your skill level and you have your game plan.
Casual observations from my own research (also chose to not pursue poison):
1. There are some freebies in Abysmal, perhaps up to 56, where the merchant gives you the components, you do the combines, and turn in the results for skillups. Can't beat free.
2. Reduced Amber Resin (triv 62)
3. Atrophic Sap (triv 98)
4. Powered Banality (triv 140)
5. Beast Choker (triv 172)
6. Metallic Alkaloid (triv 215 --- lots of sub-combines, but all purchaseable)
These, or others of your choosing, should keep you busy for awhile.
