I6: Castle Ravenloft
This campaign is using the Unchained Disease and Poison rules.
Additions to the Unchained Poison rules…
Once a poison is cured, a successful Heal check (at the poison’s DC) can reduce the poison’s severety by one step toward Healthy. This takes one hour and uses one use of a healer’s kit. This use of the Heal skill can only be done once per day on a given ongoing poison effect. The healer may use one dose of Antitoxin in addition to grant a +5 alchemical bonus to the skill check.
A lesser restoration spell automatically reduces the severity of an ongoing poison effect by one step toward Healthy.
