Check (Involuntary Change): An afflicted character must make a check at moonrise each night of the full moon to resist involuntarily assuming animal form. An injured character must also check for an involuntary change after accumulating enough damage to reduce his hit points by one-quarter and again after each additional one-quarter lost.

On a failed check, the character must remain in animal form until the next dawn, when he automatically returns to his base form. A character aware of his condition may make one attempt to return to humanoid form (see below), but if he fails, he remains in animal form until the next dawn.
Q 503: So, am I correct in my understanding that a lycanthrope cannot assume hybrid form until he is aware he is afflicted with lycanthropy? And it is also impossible to assume hybrid form without assuming the alignment of the lycanthrope strain in question (as it appears there is no way to involuntarily assume hybrid form)?
Q 504: Suppose an afflicted lycanthrope took 1/4 hp damage, thus triggering a control shape check to resist changing shape into a wolf. The DC is 20. The DC to assume hybrid form is 15. If he gets a 17 on his control shape check, could he then choose to assume hybrid form rather than animal form, or does that take a seperate check? Basically, can he do well enough on the check to "partially stop" the transformation into full animal form? Would this be a legitimate way for someone to achieve hybrid form without assuming an alignment change?
