Thanks that worked great, I just added Crippling Strike with SK so all is well.

Installing Thief High Level Ability revisions after the Tweakpack had no effect.

One thing to note - when Aran takes you to Seida, it will be midnight or so. During this time and the time that you talk to Aran in the Thieves Guild, there is an interval as the clock "fast forwards" - that might result in your Buffs being removed (similar to when you visit the Graveyard to meet Bodhi for the first time, its automatically set to night time)

To check this, simply do the scenario, and take note of the time when the fight Starts. From there, instead of talking to Aran at any time, talk to him about 1 hour before - that will ensure your longer buffs stay on. (Don't do the 1-x rounds buffs, those will probably be gone)

I'm afraid this is not the case for me, the game advances a whole day in my game so even long lasting buffs like stoneskin are gone.

if Edwin is dead / does not show up, depending on a decision you made earlier, either Cowlies or Shadow Thief Mages will warp in. They're inconsequential since they use default AI

They are just as bad as Edwin if not worse. Since they spawn straight away they start casting Time Stop which continues in the brief cut scene where the party approaches Seida so as soon as the dialogue finishes the casting is finished. This is followed by Imprisonment followed by a Spell Trigger with Disinigrate, True Sight, and Dispel Magic. So already I'm down at least one party member and my PfMWs are gone.

I tried some disabling spells, with Malison, Slow, Monster summoning in a sequencer but it didn't do much. It's not a case of me concentrating on my objective since I'm dead in 10 seconds.

It's a shame because I think this fight is literally impossible as it stands, and until this fight this one one of the best mods I've played. I'm just going to ctrl+y and ctrl+r my way through it.

Thanks for the quick reply, I'll definately try some of the disabling spells and I think I'll have to kill Edwin beforehand.

Although I have 2 mages the thieves don't appear to have any favourites in deciding who to backstab, Kiyone is usually one of the first to go. If I can survive a little longer to reposition my party hopefully they'll concentrate on Kova and Sola with PfMW.

Also sorry you didn't answer this but are my buffs supposed to disappear or not?

I started again anyway, I hated my PC and I hated Saerileth so I'm enjoying it a bit better than last time. It's not that bad since I've just done all the sidequests I missed before and not repeated the ones I had done. Thanks anyway.
