technically a full cost karma is as good as a min costed karma for the simple fact that you're going to field her in specific instances that generally involve boss monsters. Most of the times boss monsters don't rush (i think solanos event had black oni rushes tho) , so you shouldn't have that much trouble fielding her.


Still , as a freemium , there arent many black units we have access to , so i'd try to get her at least a couple CRs to make her better...
