Lycanthropy rules, based on the Turn Undead table

A simple system for player characters infected with lycanthropy!

 

There are two types of transformation: voluntary or forced.

Forced transformation happens under setting-specific circumstances: full moon, passing of a comet, meteor shower, drugs, anger or stress, trigger word for hypnotic suggestion, etc.

The player must roll on the following chart, 2d6 for voluntary transformation, 3d6 with “disadvantage” (roll 3 dice, keep the 2 worst).

	Lycanthrope type (HD) **
Level *	Wererat (3)	Werewolf (4)	Wereboar (4+1)	Weretiger (5)	Werebear (6)	Devil Swine (9)
1	-	-	-	-	-	-
2	11	-	-	-	-	-
3	9	11	-	-	-	-
4	7	9	11	-	-	-
5	T	7	9	11	-	-
6	T	T	7	9	11	-
7	D	T	T	7	9	11
8	D	D	T	T	7	9
9	D	D	D	T	T	7
10	D	D	D	D	T	T
11	D	D	D	D	D	T
12+	D	D	D	D	D	D

 

- = transformation and uncontrolled rage for a number of rounds equal to double the Lycanthrope HD, then transform back and crash (unconsciousness for 1 hour)

11, 9, 7 = roll equal or higher to retain control for a number of rounds equal to character level, then rage for a number of rounds equal to Lycanthrope HD, transform back and check for crashing (save vs Petrification or lose consciousness for 1 hour)

T = transform and retain control for a number of rounds equal to character level, then transform back; unable to transform again until after a night’s rest

D = transform, retain control and transform back at-will, no crashing

* Reddit user Maz437 proposed an addition to the system: 

This is based not on absolute character level, but on "levels spent with the curse".

However, that also means that mightier high-level characters (who level slowly), will spend a LOT of time trying to learn to control the disease, which is also a bit strange (logically, a high-level character would have an easier time retainig control).

** HD values based on OSE. Modify as needed...
