A moonbound werewolf’s lycanthropy is closely linked to the cycles of the moon.
In addition to the changes for the lycanthrope template, make the following adjustments to the base creature.
Challenge Rating: Same as a normal werewolf (however, depending on the cycle of the moon, the CR of an encounter with a moonbound werewolf can shift up or down by 1).
Defensive Abilities: Regardless of whether it is a natural or afflicted lycanthrope, a moonbound werewolf gains DR 5/silver in animal or hybrid form. When the moon is near full, this increases to DR 10/silver; when the moon is full, it increases to DR 10/silver and magic; and when the moon is new, the moonbound werewolf loses this damage reduction.
Special Qualities: A moonbound werewolf gains the following special quality.
A moonbound werewolf gains benefits and drawbacks based on the current phase of the moon. For the purposes of this ability, the moon is in one of four phases at any given time: full, nearly full, new, and other. The moon is full for the 3-day period when the moon appears the largest in the sky, it is nearly full for 4 days before it is full and 4 days afterward, and it is new for a 3-day period when the moon appears the darkest in the sky. The “other” phase encompasses the rest of each month. GMs who need to randomly determine the phase of the moon can use the table below.
Ability Scores: When the moon is nearly full, the moonbound werewolf gains +2 Strength and +2 Constitution in human form, and the bonuses he gains in hybrid and animal forms increase to +4. When the moon is full, the moonbound werewolf gains +4 Strength and +4 Constitution in human form, and the bonuses he gains in hybrid and animal forms increase to +6. When the moon is new, the moonbound werewolf has –2 Strength and –2 Constitution in all forms, instead of the normal +2 bonuses.
