OK,ok,ok.. I know what your thinking, "Ermergerb, another person created a thread complaining about Scorches patheticness" . Well, your half right. I am not just saying that he needs an upgrade (Gee, here we go) but I am suggesting WHAT should be the upgrade.
I think Scorches AA should have 3X the damage absorption as well as grant a +3 second invulnerability once activated. (AA: Dragon Scales) Naturally this AA buff will be on Nekro as well :/
His stats require a +9% DMG Bonus, +250 HP and +12% Dodge.
Just my opinion
