(SLIGHT SPOILERS AHEAD)
While I was feeding my cat, I was letting my party auto figure a path back to the Lucian Shrine from south of the Castle Fort you save Gareth at. It's in the marshy area further south of the bridges with ladders going up and down that is directly south of the Castle draw-bridge.
The Red Prince picked a path through the MASSIVE group of enemies about thirty yards from the second bridge. All undead except this Naga looking Voidwoken. My other characters made it so I've tried luring them North and killing a couple.
They are all one level higher and have good AI here. Plus, the Huge Voidwoken can port himself... I thought I was saved because he couldn't climb the ladders to get to me.. nope.
I tried sneaking in from East of that area and can get to The Red Prince there, but it's no good. I aggro all of them the second I restore him because he is directly in the sight of the big Voidwoken and two other mobs.
I really need some good advice here from some better players than I am.
I'm grateful for all and any feedback you may think helpful.
