Vindemiatrix is scheduled to release this Thursday (next 10 man battle). Like usual I'll have a more detailed guide and video up on Thursday, but some early pointers:
Swaps between physical and magical immunity every 10% health in phase 1 (above 50% health), you need DPS of both types
Has a threshold every 10% above 50%, and the HP locks for each of them
No more HP locks after the 50% threshold, you can OTK from there if you have the firepower
Other than one AoE physical during the 20% threshold, everything physical is single target, so a provoker + magic cover is the desired setup
All magical damage above 50% is non-elem, all magical damage below 50% is wind (with a -100% wind imperil)
All breaks work, boss is beast + undead hybrid
At 50% and below boss begins using ST death, give your provoker immunity
Uses aoe sleep as an ambush and on thresholds above 50%, uses aoe paralyze on thresholds at and below 50%
AoE dispels you at 50 and 20% thesholds
Always immune to holy, goes immune to fire/ice/thunder/water between 70-80% hp only - dark/wind/earth always works
