Hi!
There is only one contribution tier in the Merry Mayhem Solo instance. You need to have 100% contribution to receive the Strongbox when the instance is completed.
Hi!
Merry Mayhem is still a Calypso event and activity counts towards CLD revenue. Avatars from other planets count as being on Calypso while they are in the solo instance, exiting the instance returns the avatar back to where they entered from.
The FFA instances can only be entered by talking...
