Concept:
The concept is to deal the same damage as a Dragonslasher, yet damaging dangerous foes with Pain Inverter (as obviously suggested in the title build).
Attributes/Title Ranks:
Swordsmanship: 12 + 1 (helm, can use sup runes)
Strength: 10 + 1
Tacs: 8
Asura title: 3+ would be good ( I have R4 asura)
Optional Attributes/Title Ranks (used when appropriate PVE skills are used):
Dwarf: Any
Skills:
[ Optional ]
[ Optional ]
Dragon Slash
Flail
Enraging Charge
"For Great Justice!"
Pain Inverter
Insert res/any skill here (I use Rebirth for HM, cap sigs for NM)
Skills to go in Optional:
An attack skill
Great Dwarf Armor (useful on Destroyers)
Basically any skill you want ^_^
Strategy:
Basically works like a Dragonslasher, except you have one new dangerous asset in your arsenal: Pain Inverter. Since the skill damages [insert target foe here] every time it deals damage, this is a new, innotative skill to use in HM on dangerous and lethal bosses to basically kill themselves if you can keep the enchantment up.

Just a final word... please give me constructive critisism as to how I can galvanise* this build.
*By the way, galvanise means to strengthen, or to add strength to.
