Apparently the test information hasn't filtered over. Here's the final damage from a series of 7 tests using 6 blms (each using different gear, and varying cast order each time to determine the combination effect), courtesy of Byrth:

Yes, 60k damage from 6 blms, so an average of 10k damage each by contributing to this spell. This is not a solo spell, but it's far from useless.
