For stack Erradication + Roaring Blaze (i dont mean stack multiple Roaring Blaze tho), which is the more efficient way to doing it:
1) Having Erradication on the target before of using Immo + Conflag
2) Having Immo on the target, casting Chaos Bolt, then casting Conflag
This is mostly for avoid SS overcap, but is useful knowing it for other situations.
P.D.: sorry if is hard to understand the question, have some troubles trying to finds the right words.
