On normal with a level 5 party it's pretty easy. I think it could be done at lvl 4 with Kana and Sagani added (maybe without Sagani). But there is a fair reason to wait until lvl 5 - one can run the entire area, killing everything, and wind up with a ton of loot. The armor and weapons alone add up to a lot of coin. And it is very handy while fixing up Caed Nua, getting hirelings, etc. For the final fight I have generally used the tactic of setting up in the room across the hall from the Throne, setting a trap in the doorway, and shooting the nearest guard. Then they come into the trap, get hit with a fireball, and with Durance set up properly, iconic projection and it takes the fight out of them. Last time I pulled everything in the Throne room except for Raderic, so I was able to zerg him. Kinda funny with a full team on him, plus summoned skels. Poor bastard.
