"Escape to Salvation" - "Magnificent Retreat" [Campaign 4, Mission 4]

Boris K, at the end of the 3rd mission (about the dragon)
It's good that there's a save... :p
I'll have to go back and replay it :(
Wulfsten has:
Runic Battle Axe;
Runic Battle Armor;
King of the Dwarves Greaves;
King of the Dwarves Shield...
and also the Amulet of Mastery and the Lion Crown...

Zeheer can give him the King of the Dwarves Cuirass
Zeheer has a lot of artifacts, is it worth giving the Ring of Sar-Issa to Wulfsten?
Zeheer has many "dragon" artifacts, but will they help
Wulfsten?

P.S. I deleted all the saves for the 4th and 3rd missions, :(
and started the 3rd one again, I need to level up Wulfsten:p
