Elemental Reset sets the element of all attacks to neutral. That probably means the fire staff wont affect it anymore.
As for damage on neutral mobs, I calculated with clean equips that a lukless flame wizard with a fire staff does 33819~44459. With 50 magic attack more it becomes 36993~48303.
O wait, thats with 40% amp, Flame Wizards only have 30%... That shaves off around 3k damage, getting around 34k damage min. Just a rough calculation, but they probably can 2hko Jr. Newties and 3hko Nest Golems.
