ingested (toxin) - 600 gp
This poison that looks like syrup has a strong sweet taste and a peach smell. It causes degradation of the walls of the blood system. The effect occurs about half an hour after ingestion.
A creature subjected to this poison must succeed on a DC 13 Constitution saving throw or be poisoned for 25 + 1d10 minutes. At the end of this period, the creature's hit point maximum of the creature is reduced by 1d10. Any magical healing restores the hit point maximum.
