Does the guild tribute, "Fury of Conquest" affect dots? The description says it affects all damage but then it says it affects spell damage, which isn't all damage, and does not say specifically that it affects dots.
The Improve All Damage focus effect ought to be nearly non-functional for nearly all spell casters, as tributes are "worn" focuses. IAD will work on dots, but only if you don't already have a worn focus effect with a higher max modifier than 20%
