The Table of Poison Side-Effects

Years ago, I made a poison side effects table to make it so that the application of deadly venom was more than just “take extra damage, optionally with a Constitution save to negate it.” I’ve also used it as a random herb or wild plant ingestion table to make uninformed foraging more… interesting.

So here it is, my expanded poison/toxin/venom side effects table. Use with care, death is possible.

The saves are listed in Erwinian System scores, but can easily be adapted for other systems with some eye-balling.
