Mangix doesn't hold to it by rule, but he vaguely recalls an old master musing that, if one could manage, scaring up a companion was always preferable to drinking alone.

Moon Glaives can be activated to create 4 glaives that rotate in a 175 radius around Luna for 7 seconds, reducing damage she takes by 25%. Any unit that collides with a glaive will take 75% of Luna's Attack Damage.
Ability Disjoint Notes:
Does not bounce when disjointed by the primary attack target.
When disjointed by a secondary target, the disjointing unit is not registered as hit, the attack may immediately bounce on it again if its within range. The disjointed instance still counts towards the bounce limit.
Carefully sharpened, Luna's boomerang-like weapon cuts a wide swath through enemy numbers.
