Return of Reckoning

hi, is invader for we worth it?
or should i go for the vanquisher sentinel helm+jewel combo??
also what weapons should i go for?

General advice for all DPS classes: Min-max and combine sets and talismans/potions until you hit around 1030 of your main offensive stat, look for fast weapons (the lower the number in speed, the better), and get critical from renown.
