Well it sounds like it's not so much to help the RUN as everyone else in the alliance. Assuming it's fairly potent a single RUN might be able to more or less negate magic dmg/debuffs for a time. Almost like a perfect defense but without physical and as a debuff so it helsp everyone fighting the mob. Of course on the assumption that it is potent enough. If not then it's probably only going to be good for idk adl lol
