*Tips*
I Did This On Obelisk, In A Quick Run.
- Trinket "Blessing Of Misplaced Nobility" For An Extra 2 Shield Per Turn
- Look For "Gain Shield On Use" Augments For Your Skills
(Example: Shield Bash Augment "Gain 2 Shield On Use")
- Try To Get The "Bastion" Set Bonus For An Extra 3 Shield Per Turn
- Shield Potions Are Very Helpful (+10 Shield This Turn)
- Smoke Bomb And Shield Wall Bindings, For More Damage Mitigation.
Also, I Did This In Two Man Co-Op.
- My Partner Died On The First Boss, Mitigating Some Damage.
I Used Plus Physical Attack Vestiges And The "Shield Bash Does 50 Extra Damage Per Shield You Have" Augment For Damage, After I Got The Bastion Set To 4.
Hope This Helps.
Good Luck!
