This's a new feature for difficulty mode created by me hope you like it, Where you have the chance & only 1 chance at the entire game to create an enemy and the strongest ever enemy at the game.
Recruite the Ironbull, Don't do his quest Demands of the Qun or do it but you must sacrifice the chargers so you can fight him at Trespasser DLC.
Turn Walk Softly trial on.
Turn it to the lowest difficulty, You can get potions if you want.
Now to the important points, Before you travel to the darvaraad which you'll encounter the ironbull, Equip the ironbull with weapon & shield, Craft the weapon with Silverrite fade-touched grants him 5 guard and the shield with fade-touched Veil strike, His armor must be more then 300 armor rating and crafted with fade-touched chances to inflict Immolate or lightning damage.
Spend his skill points at all the shield skills, and Horn of valor with it's upgrade 10 % guard, if there's more skill points spend it on any ability provides guard.
Guys, I was playing on the highest difficulty when i tried it, Then i lowered the difficulty to hard then normal then i turned the Walk Softly trial off, I almost killed him, I couldn't, There's No Hope, Not a Nightmare, But A NO HOPE.
