So I'm playing on master difficulty and my fire breath shout does next to no damage, is any other way to make it more powerful besides dragon aspect and meditating on the word of power? Does argument flames perk do anything?

I was also wondering about the new dragon priest mask and fortify destruction potions as well? Sorry for all the questions but I haven't found anything solid on the net yet. Found few e things like fire breath improving destruction skill which seemed intresting if that is true.

Thanks guys for any help

I just use mods that fortify magic shout damage scaled to something, like dragon souls or something else.

Augment flames should work.
Fortify destruction potions probably wouldn't, since dragon spells usually aren't marked with a skill tag
Also the single word shout has slightly better DPS than the 2 or 3 word shout, because you can use it more often.

Ask Parth to explain Yol to you.
