np ... and the EP explosion seems to stack. I haven't done proper testing, but leveling 1-70 in S2 was enough to tell than 4 EPs on a mob does far more damage on explosion than a single EP. Since single monk EP was blowing up everything, I decided to round robin EP to manage better my Spirit. That worked fine in lower levels and in Hard but in Master/T1, it was not enough to kill full packs of white mobs. Deleted the round robin and I was blowing packs again. Tried a few times with same mobs in the same map and the results were consistent. 1 EP on explosion, left whites with like 10-20% health. 4 EPs blew the whole pack every time.

Again, not really proper testing but it was a noticeable difference.
