Thanks so much for posting this! I’ve been told about corruptions, mostly told to remove corruptions, but I never understood how they worked. And usually had to fumble around looking for my corruption removal skill.
I’ve now made a point to find my corruption removal skills on each class I play. Another useful skill to find is interruption. When a foe has an orange ring underneath them, they are inducing and you may be able to interrupt that induction. I first learned to recognize this ring when fighting a dragon roving threat – the ring is really big!
