Tested this on Agnarr, (65 level max) on a wavecrasher in Paw. They self-heal so if only the tank engages this mob can be up a long time.
Three wizards in group and they all cast this once tank got aggro. These pets die instantly if they get aggro otherwise they appear to last forever.
Over the course of the fight the three swords did 5025, 4269 and 3819 points of damage. One wizard is max aa and the other two only have around 50 so this may account for the differences.
Max hit was between 70-90.
Average hit 52-54.
DPS was 16-20.
For 250 mana, obviously a very efficient spell... IF the fight lasts this long. Which normally would only be boss and mini-boss fights. I dragged this one out. In a typical Paw fight, the mana efficiency would be inferior to a wizard just casting a regular nuke. This is effectively a dot so you can pile it onto nukes. But I rarely dot in Paw since mobs die too fast for anything but a mana-free clicky dot to be efficient and, even then, given the cast time of most clickies, it's still not worth it (unless out of mana) since you can use that cast time for a real nuke.
Get the clicky from Vex Thal and this really gets effective. But I've never seen that drop of many VT raids.*
*On reconsideration, that has a 10s cast time. The spell is close to instant. Unless wizzy is OOM, the clicky isn't worth the effort or the dkp, I think.,
