This is a simple build with one thing in mind- make Jabs as powerful as possible. It's easy to set up and easy to play, while being fun and doing good damage in dungeons to boot, especially in AOE encounters. Give it a go!
Rotation is very simple- Cast Rune for the sustain and added survivability, cast Nova for the 5% increase to class skills, then charge in with stampede to trigger the Maelstrom 2H bonus and jab away. Refresh the three backbar buffs when they run out, and swap to casting Radiant Glory instead of Jabs when fighting a boss and it's health reaches about 35%. In add packs or AOE fights just keep casting Jabs.
The Maelstrom 2H is great here, as the bonus damage applies to each hit of jabs. The perfected version will make almost no difference however, since you should spend very little time on the backbar. For the same reason any 2H weapon will do.
Velothi Amulet improves damage a lot, and makes the rotation even simpler since we won't need to cast Beast Trap for the Minor Force. If you can't get the mythic this can be swapped out for a Deadly Strike amulet and you can wear a monster set, with Nerieneth being a great alternative. Just remember to cast Beast Trap for the Minor Force if you do this.
Forest Wraith is a craftable set, and Deadly Strikes is purchasable from guild traders, making this build very easy to put together. We get the weapon/spell damage buff from jabs itself, and Camo Hunter gives the weapon/spell crit buff, so any potion is fine here. If you find it more difficult to sustain, swap the flat food for Dubious Camoran Throne for the extra stam regen. Mag regen should be fine, since Radiant Glory gives back a lot of Magicka when using it in execute.
For the CP, Force of Nature will likely give the best damage in most encounters by increasing your penetration. If your tank is using sets that debuff the enemy armour enough, swap to Master-At-Arms (Direct Damage).
Happy Jabbing!
