Not the highest level target - but was still fun to do. A few things I've learned in playing w/ this for about an hour:
1) Cure Potency doesn't seem to increase dmg, at least no where like MAB / MBB.
2) I tried adding a lil more MND and it didn't seem to impact damage at all.
3) Seemingly Arbatel +1 didn't increase damage as much as a well augmented merlinic.
4) Other than weatherspoon ring, I mainly went w/ my normal MAB/MagicBurst set.
5) I'm sure I could push a little higher but this was good enough to play with...
