Lethargy poison is commonly used in hit-and-run tactics by drow and others who want their victims alive; the ambusher retreats until the poison sets in and the victim falls unconscious. Further exposure to lethargy poison does not require the target to attempt additional saving throws; only failing an saving throw against an ongoing exposure can progress its stage.

Some character choices give access to uncommon options, and the GM can choose to allow access for anyone. Less is known about uncommon creatures than common creatures. They typically can't be summoned. The DC of Recall Knowledge checks related to these creature is increased by 2.
AlchemicalAlchemical items are powered by reactions of alchemical reagents. Alchemical items aren't magical and don't radiate a magical aura.
ConjurationEffects and magic items with this trait are associated with the conjuration school of magic, typically involving summoning, creation, teleportation, or moving things from place to place.
IncapacitationAn ability with this trait can take a character completely out of the fight or even kill them, and it's harder to use on a more powerful character. If a spell has the incapacitation trait, any creature of more than twice the spell's level treats the result of their check to prevent being incapacitated by the spell as one degree of success better, or the result of any check the spellcaster made to incapacitate them as one degree of success worse. If any other effect has the incapacitation trait, a creature of higher level than the item, creature, or hazard generating the effect gains the same benefits.
InjuryThis poison is delivered by damaging the recipient.
PoisonAn effect with this trait delivers a poison or deals poison damage. An item with this trait is poisonous and might cause an affliction.
SleepThis effect can cause a creature to fall asleep or get drowsy.
