The gear here is similar to the Optimised Dungeon Tank Build.
Dragonstar Arena is very low incoming damage for the Tank because it is such old content now designed for 160CP on the old system.
This means running a maximised setup with Powerful Assault and Olorime is quite easy to do. For additional safety switch PA to Yolnahkriin and if you have a Healer use PA and Yolnahkriin.
You could use War Machine or Drakes Rush here if you have certain sets on the healer or you want to try to maximise damage in other ways.
For the monster set its a simple Encratis’s Behemoth for Magicka or Tremorscale for Stamina as these both buff DPS.
If you are new to DSA then you could use Leeching Plate but make sure to use at least 1 group buff set with this, any of the previous mentioned sets or Worm Cult but ideally Yolnahkriin.
Use any class here, it doesn’t make much difference.
Pretty much any race is playable here. Imperial or Nord would be best for the more frequent Ultimate usage.
The best Mundus Stone to use here is: The Atronach for the extra Magicka Recovery,
64 Health works well alongside the PA and Medium Armor setup.
As standard we use the Bewitched Sugar Skulls which gives us Max Health, Magicka and Stamina plus more Health Recovery.
You can use regular Tri-Stat potions here.
