On an 85 wizzy with 45% enhanced damage gear and all crit and damage AA's maxed out:
Hits for an extra 1382 x 3. Crits for 4076. Thats on top of what the original spell hits for.
I casted ethereal combustion and hit for:
16820
+1382
+1382
+4076 (crit)
------------
23660
possible max damage with 45% enhanced damage gear:
43000 (crit)
+4076 (crit)
+4076 (crit)
+4076 (crit)
------------
55228
Now that"s some damage and that's not even top of the line gear!
I should add that you can double all that with a twincast. Having used it a little more, it really seems to shine with those low mana spells like wildmagic and chaos combustion. The only bad part is the very short duration.
