Immediately upon receiving a point of limit from exposure to the light of the full moon, a Lunar may choose to prematurely enter Limitbreak rather than wait for it to hit 10 and go off naturally. (This ability conveys no special awareness of the limit track or knowledge of either limitbreak or the great curse to the character.) The Limitbreak lasts the full duration and functions as normal(uncontrolled vs partial, willpower is gained if uncontrolled) save that the Lunar comes out of it with half the points of temporary limit(rounded down).  This can be done only once in any given night.  Finally, limitbreaks set off in this way never add to a casteless's permanent limit even when triggered within the Wyld.

If Limit gained from moonlight was enough to finish filling her track and cause limitbreak, treat it as though it was prematurely triggered except that limit is reset to zero at the end as normal.

(This is Luna, goddess of madness's attempt to help her chosen with their own bouts of insanity and loss of shape, (although she is not truly aware of this and does not recognize the curse for what it is), not some weird werewolf thing shoehorned in for no reason.  Yep.  Definitively not just a werewolf reference ;)
