A spell designed to help tanks or healers or damage dealers or even themselves from ridiculously overpowered AoE's that have been the trend in Voidwatch and now also Legion(from my observations of the test server runs).

Fortuity
Level 96
Makes you immune from Severely Damaging Attacks.

Basically a similar effect to Earthen Armor/Scherzo or Migawari but single target and castable on others.

Realistically I can see SE stealing this idea and making it self-cast on RDM and giving WHM an AoE version called Fortuna, screwing RDM out of unique spells like they did with Gain and Boost spells. :/
