I've introduced unchained affilctions rules in my home game, and I've gotten some concerns from my players.
Specifically, there really aren't any effects in the existing rules that can offer relief from the ongoing poison effects other than time or high-level spells (neutralize poison or heal.)
I'm considering the following homebrew rules and was wondering what others thought...
Antitoxin: This oily, bitter-tasting alchemical remedy can be used in one of three ways: Preventitive Grants a +2 Alchemical bonus to all Fortitude saves versus poison for 1 hour. First Aid While actively poisoned, you may take a dose of antitoxin to allow you to roll twice on your next saving throw versus the poison, and take the better result. Restorative You may take a dose of antitoxin to alleviate the aftereffects of being poisoned. Make a saving throw against the poison's DC; success indicates that the poison's effect drops by 1 level after an hour. If the save beats the DC by 5 or more, this happens in just 10 minutes. Only one dose of antitoxin is effective for a given poisoning.
Heal skill: Recover from poison You may attempt to alleviate the aftereffects of poison. If you succeed on a Heal check against the DC of the poison, the poisoning effect drops by one level. This treatment takes 1 hour. A creature may only recover from poison in this manner once per day.
Lesser Neutralize Poison
School Conjuration (healing); Level bard 3, cleric 3, druid 2, paladin 3, ranger 2, shaman 2, witch 3
Components V, S, M/DF (charcoal)
Target creature touched
Saving Throw Will negates (harmless); Spell resistance Yes (harmless)
You detoxify some of the venom in a poisoned creature's system. If cast on a creature actively poisoned, the subject automatically makes its next saving throw against the poison. If cast on a creature who is suffering the aftereffects of being poisoned, the subject may make a saving throw against the poison with a bonus of +1 per 2 caster levels (max +5). Success indicates that the poison effect drops by one level.
