Magician %/s (KMS FLY 2 & GMS Dawnveil)

AFAIK, Infinity, Amplification, (and while they're not mentioned, Elemental Weapons) do not affect DoT while elemental weaknesses do. I'm going to take a wild guess and say Storm Magic and Arcane Aim won't either, but I'll go and test it to make sure since assuming it is never a good idea.

Edit:

 Spoiler

Hope that's sufficient proof that Arcane Aim and Storm Magic don't affect DoT.

Alright, thank you for clearing that up.
