The witch at the far North...W....T....F?

[Leviathan]

I ended up just walking around the isle (Reaper's Coast )(good thing I had a save game not far) and there is that crucified witch that is burning and circling around at the very tip of north Before that island.
So I tried to get by, but the game threw me into a conversation. I failed persuation and the witch finished off my entire party in one move. I tried it a frew more times to see what's up, but it casts a spell that just kills everyone without a chance to even take a turn.
I'm level 14, not sure what level that is not even sure how am I ever gonna get by if the game won't even give me a chance to take my turn, regardless what level I am?
Same deal with the crazy sourcerer just behind it, in the stone ruins, Hannag- or whatever, I supposedly talk to him, but he just fries me when I approach.
These kinds of stuff kinda discourages me to continue playing this game.

I'm level 14

There's your problem. Alice deals approximately 3.5k of damage in her first turn (on Honour, at least - could be less on lower difficulties), so ideally you want to tackle her at level 16/17. Alternatively, attack her with magic from afar to drag her away from the idols - there's a good chance she'll waste her turn moving towards you instead of casting her deadly magic.

With Hannag, you just have to be stealthy - use Chameleon Cloak, sneaking, teleport right next to her. Direct approach doesn't work.

#1 Alice is an optional fight. She's probably one of the two hardest fights on Reaper's Coast and too much for a level 14 party.

#2 The key (for me, anyway), is to teleport Alice away from the fire. The fire heals her. Have your tank down a fire resistance potion and/or do other things to improve magic armor.

#3 Rain!

#4 Teleport her next to your tank (if it's your tank that has the teleport ability, so much the better), and have the rest of your party spread out AWAY her starting position. Stashing your archer in the ruins overlooking the area is a good idea. Once the fight initiates, she's going to go first. If she's next to your tank and the others are further away, it limits what she can do in turn one. She seems to have a lot of AP and can move, do a high damage fire attack, and take control of one of your characters in a single turn if she starts close enough to everyone.

#5 If your tank can survive her initial attack and she couldn't reach anyone else, the fight is probably over. You should be able to get her armor down and cc her in one turn. She doesn't heal away from the fire and her fire elementals won't be able to reach you.

I couldn't quite manage this takedown smoothly with a level 15 party, but I'm no expert. She still managed to kill one of us, but that's what resurrection scrolls are for I guess.

Regarding Hannag, it seemed more advantageous to help her by helping her fight off the magisters instead. She has a nice quest for you afterward and becomes a handy merchant.

Give your intelligence based character a shield and best armor.

Have rest of your party all do physical.

Send the intelligence based one in alone to the witch. (Do not get rest of party into combat)

Witch nukes your intelligence character, who will survive.

TP witch to the rest of your party.

Murder with physical chain CC.

Also did this at level 14.

Or, even easier, prevent death with necro for your first character, so you can send in whoever and still survives.

I just teleported her down onto the beach and killed her before she could reach anyone. Might want to unchain someone and send them into battle first because she does a powerful AoE attack.
