Fade Touched Everite for healing. Mandatory on pretty much every mage imo. You heal for 25% of all damage you take, whether it be to guard, barrier or health. Avaar rogue going to one shot you? Guardian spirit and Fade Touched Everite will save you, healing you back to max within a few seconds.
Fade Touched Plustian Velvet. Hidden Blades proc is super good on every class. Free precision detonator too.
Fade Touched Nevarrite (On death: Target explodes for 75% of weapon damage) Perfect for Rogues. Wait, so you take 75 % of my killing blow and apply it in an AoE around the target? Amazing.
Fade Touched Dawnstone. Best anti death defensive masterwork in the game. Guard on hit wont save your rogue from being one shot. Pure invulnerability will.
Fade Touched Varghest: 20% damage bonus if not hit for 5 seconds is great on mages/archer rogues.
Fade Touched Bloodstone: 7.5% extra damage for each surrounding enemies is godlike.
Most overrated masterwork is probably guard on hit. 5 guard isn't going to save squishy classes, and is now even more redundant due to new Horn of Valor.
