what happens if in the way begging before imeon gets captured she dies?

doesn't she run away when she gets too hurt? she runs away and finds her own way out so she can be there to get captured. that might be thier way of preserving the story line

What if you cast Disintegrate or some other instant kill spell. Or you could just hold her and ´kill her, anyone tried that before they got ot of Irenicus Dungeon?

No, nothing will kill her!

I have tried (I was bored)

1. Trapping her against the wall and beating her for 5 minutes (Everone had STR25, a good sword, and was a level 40) she survived this despite several criticals!!!

2. Imprisonment doesn't work

3. getting here to leave when you have the portal key doesn't work

4. She opens doors to escape

5. Power Word:Kill doesn't work

6. She automatically saves (or is far far too lucky) any instant kill spells (finger of death, disintergrate, polymorph other etc.

7. She can survive 90d6 damage with one hit point (robe of Vencia, lvl 40 mage, amulet of power, time stop spell, 6 fireballs)

So as you can see, unkillable

... and then when she rejoins your party, she can't take a simple love tap from a gibberling without bursting into tears ..

If you really want her dead early on and don't mind cheating, trying using Shadowkeeper to remove her belt and then beat up on her. I've heard that the belt she has in chapter 1 saves her from harm. I'd be interested to hear if this works and what effect it has on the game.

get yourself the "killsw01" and feel her blood splatter all over your face... I did it and it felt good.
BUT SURPRISE, SURPRISE. COMING OUT OF THE DUNGEON THERE SHE WAS JUST IN TIME TO GET ARRESTED!!!!

Give up, guys. Long story short: there are two Imoens, the one at the start with a belt and the other one who appears outside of Irenicus' dungeon at the start (and also later on in Spellhold), and you're never going to get rid of her. Not at the start of the game, anyway.

NNNOOOOOOOOOOOOO I want her DEAD!@!!@@!!!!!!!!
