I've been doing quite a bit of testing today with the relentless set. 18% chance to get extra turn.

I equiped Lady Rowan, Banner Lords, with this set.

She has 3 skills.

1. Slash, single target, 1 hit
2. Scourge, 3 random targets, 1 hit
3. Blade Surge, single target, 4 hits

I've read in the guide section of this forum that the chance goes down from 18% to 9.5% to 5.5% on successful triggers.

How does this set work with aoe skills and skills that hit multiple times?

If it's an aoe skill that hits all 4 targets. is it then 18% x4 = 72% chance on extra turn? Or is it only the 18%?

Because it doesn't seem to trigger more often on Rowan's multi hits. I've actually seen it go off on her Slash skill the most.
