Zefah said:Are you using Morrigan? Her Vulnerability Hex spell (resist debuff) is extremely effective on more powerful foes. Cast that on them first and then follow up with Winter's Grasp, Lightning and Drain Life for some massive damage. Doing this will almost certainly pull aggro on Morrigan, though, so have your healing poultices ready or a party member that can taunt the enemy off her.
Ill look into getting the Vulnerability Hex soon as it was one of the spells I was looking at. Also im not using Morrigan as Im still in Ostagar. But I dont plan on using her in the long run as I kind of wanted my companions in my first run to be a hexing/healing mage (PC), rogue archer (Leliana), Tank (Shale), and Damage-Giving Warrior (Probably Alistar).
