I've been using [armory]Ill Omen[/armory] with [armory]Cold Steel[/armory] to see if it's any good. I discovered that [i]Cold Steel is not applying Slow on kills.[/i] This is true for both Ill Omen and Zephyr. If my memory serves, it used to have that feature? Additionally, Ill Omen's heavy attack is not applying any Slow. Slow also generally feels inconsistent, sometimes not being applied whatsoever when it should. The method I used to check for this was visually studying the enemies I struck for the Slow debuff, and in case it wasn't showing but still applying, I was running Prismatic Hunter with Stylish Executioner so Slowed enemy kills would make me invisible.
