If a character has Delay Poison cast on them before being hit by the poison, my understanding is that both fortitude saves are delayed until the Delay Poison wears off.
If a character is hit by Drow Poison, and fails their first saving throw (which results in unconsciousness), what happens if the character has Delay Poison cast on them during the first minute after failing the first saving throw? In that case, the need to make the second saving throw is delayed until the Delay Poison wears off. But do they regain consciousness in the meantime? And if so, does that happen as soon as the Delay Poison is cast, or after the first minute has elapsed? If they don't regain consciousness, would there even be any benefit to casting Delay Poison?
The relevant portions of the SRD:
An opponent hit by a drow’s poisoned weapon must succeed on a DC 13 Fortitude save or fall unconscious. After 1 minute, the subject must succeed on another DC 13 Fortitude save or remain unconscious for 2d4 hours.
Delay Poison: The subject becomes temporarily immune to poison. Any poison in its system or any poison to which it is exposed during the spell’s duration does not affect the subject until the spell’s duration has expired. Delay poison does not cure any damage that poison may have already done.
