Since heavy maces special ability already silences, we don't need sacred ground. Also, for playing in parties, defensive slam is the better option than threatening smash.

Honestly, anything here is a good pick, but when focusing on dungeons, snare charge is the way to go. It also helps this build with dungeon bosses, where you focus on a single enemy. You could use air compressor to pull in enemies for the silence, but leaping to the enemy and rooting, providing the same result but better, it's obvious what to pick.

Now, this cant be changed, but that's all good, because this is what this build revolves around. Being able to stop enemies from using abilities, combined with rooting from snare charge, makes any enemy completely vulnerable for at least 3 seconds. It might not seem like much, but 3 seconds can change the tide of a battle.

Your entire goal isn't to deal a ton of damage, but to provide opportunities for team to attack, so you need to survive for as long as possible. Life leech does that.

Once again, your playing in a party, so a shield for all your teamates, especially if your about to die. Also, it's basically just the much better version of energizing shield.

It's pretty basic, but full toughness build helps you survive, even for a second longer.

To be frank, ensemble aura is great, and probably the better choice for bosses, but taunt is crucial to making sure the enemies focus on you, and you alone.

Toughness all the way
