Were triggering
From War Thread
Weres who are not yet able to change shape need to be triggered before the gain both the positives and often the negatives associated with being a were. Somewhat ironically Jane Stewart triggered herself by using Bastian magic which acted as a combination of infliction and parental triggering.

If you have a mooncurse which is different to the form you are in you will be forced to change into your moon-curse form, unless you have taken the right dose of deadly nightshade, or had it suppressed when you were young. It is harder to supress as you are older or after the change because you need more of the active element in deadly nightshade to suppress the change. This means it becomes more likely to poison a were.
==Infliction== This is not so much inflction as triggering. It requires quite a remarkable set of circumstances but it does happen. The were must be of the same type (A were-ferret could trigger a were-skunk, but not a were-cat). The triggering were must also be feral and have the same mooncurse. This overrides suppression by deadly nightshade
==Parental trigger== This in Elled has become the most common method A parent uses a small amount of natural were magic to charge their offsprings blood. This enables the transformation to take place in a controlled way. Not as much magic is needed as for the infliction method though.
Parental triggering is basically a controlled infliction. It has no effect on someone not related to you. It does not have to be a parent. Jane Stewart when she released uncontrolled magic triggered herself.
==Technical triggering== If a were is changed out of the shape they have they spring back to their mooncurse form. Not many are missed but some are.
