I know this might not be very Sith of me, but just finishing this guy solo, and then assisting another Sith, I figured i'd give a bit of strategy for those who might be having trouble with this mini-boss type enemy.
Well close to the end of the Balmorra storyline you will face this guy which is pretty simple to beat.
As always having your Saber Ward and a Fresh Medkit helps and should be free, just know once you start this fight, primarily rely on your companion for the DPS side of things and just focus on utilizing your Disruption skill when Rylon starts his Firebomb.
If you don't miss a firebomb with Disruption, Vette will drop this guy in no time, just rinse and repeat,.. should have to Disruption his firebomb attack about 3 times and then the fight is over.
If you miss one then of course hit Saber Ward, and your Medkit and just follow the recipe.
