Charge, cleave, carnage, disengagement attack, riposte all can trigger skald special thing. Only carnage of these is not an 'attack' so it won't trigger weapon proc on hit, and won't generate focus for cipher. All the rest will.
Are you sure carnage can trigger it? Because I noticed when I made a howler in the most recent beta none of the carnage hits would crit, and I mouse over'd them and saw that one of them rolled a 99, so was over 100 after all the to hit calculations, and it still didn't crit. Did they remove carnage's ability to crit?
Also, does anyone know how big carnage's AOE is when you pump INT to 18 vs leaving it at 10?
Thanks!
