Stuck on " The Reason Roaille"

[Elmeron]

Cleric Stance is a massive increase in damage, so that should help a lot! Shadow Flare is actually really helpful here, since it has a DoT and a slow effect. Make sure you're using Bane to spread those DoTs around, too. Miasma has the Disease debuff, which makes mobs move slower and regain less hp from healing magic.

Yeah, first time I switched to Cleric Stance and followed the original strategy guide I described, I was able to clear it.
