If you really wanted to min/max, then you could just kill the first bomb and ignore the others. That would work fine.
Some adds in this game can be successfully ignored, like the second boss in Temple of Qarn HM (except the guardian of course, gotta kill him) but i would not consider the first snowcloak boss one of these instances
