Acid Purge vs. Flames of Ignaffar, and can Seal be used offensively?

[tqFan]

Spammable item based spells that can deal significant damage in my opinion. No Resistance debuffs / spells with cooldown here - but rather the ones you can more or less build around, preferably with high casting speed.

Since I put Corruption in the table (mainly because it’s from easy-to-include component), maybe also
Mythical Codex of Eternal Storms
Mythical Arcanor, Blade of the Luminari

I don’t know Retal so not sure how good the throw skill is.
