Has your Den Leader started a raid against a fellow den?
Den Leaders can trigger raids against other dens, in which the majority of den members must participate. Allies can still raid each other, but the moment one raids their allies, their relationship will be updated on their Den profile as a betrayed status. Enemies get bonuses for raiding each other.
Only leaders can start raid battles against other dens! If a leader wishes to do so, they must have the majority of their den members participating (over 50%). If only a few participate (the minority), it will not be counted as a raid battle by the admins, and will simply be counted as pvp. To avoid late art impacting this decision, it is recommended to hold off submitting the art until the group is all ready. If an art/lit is sent to corrections which impacts this, the others will still be rolled for raid rewards.
There needs to be one art/lit submission per spirit participating in the raid, and the art must have the spirit it's being submitted for in the art. Other spirits (Allies and enemies) are not required, but the art/lit must be clear in the subject.
Only one character in each submission needs to be 50%+ showing, the rest can be minimum headshots.
Color not required, but it needs a very simple background at minimum and a fairly clean sketch.
The more effort you put into the raid images, the greater bonus that will be applied to the raid for you to succeed.
