Cursed Moon Event

The Cursed Moon Event may periodically trigger during nighttime hours. This is a global event affecting all players.
For versions 1.0.6 and above, the Cursed Moon event has been set to trigger at fixed lunar phases. The trigger interval is between 2-3 days (the previous triggering method had way too many bugs!).
The Cursed Moon Event lasts throughout the entire night and causes the following effects:
-
Mobs drop
Untreated Moondust. -
When in
Initial Form, your form will randomly change to stage 1 of aProgressive Form, reverting when the event ends. -
When in stages 1 or 2 of a
Progressive Form, your form will temporarily advance one stage, reverting when the event ends. -
When in stage 3 of a
Progressive Form, your form will temporarily revert to stage 1 of that form, reverting when the event ends. This also provides an opportunity to use anInhibitorto recover. -
Note: For some forms with special progression conditions, such as Spider Form, the effects of the
Cursed Moon Eventmay differ slightly. Please refer to the corresponding form documentation.
