Agreed, very nice idea. Give it the activation trigger from Thread of Isolation / Facet of Solitude, but apply Exhaust to that target instead of a Severing burst. It was always strange to me how Vex Mythoclast and Necrochasm got bespoke Catalysts while Touch of Malice got a perk that's normally great but offers little to that specific gun.

[quote]touch of malice's catalyst should exhaust targets when they're hit by the blight or by landing multiple critical hits on a target perhaps. This would be perfect for Touch as the exotic doesn't need another damage perk but maybe a perk for survivability outside of healing, it would also be a nice "support" exotic to help your team with damage reduction, I would love for there to be a reason to run the exotic during DPS and I feel that allowing the exotic to reduce the damage of a target would be perfect and would fit the exotics theme and lore.[/quote] Good idea.
