This thread inspired me to revisit this encounter in my patch 4 Druid run. It's one of my favorite fights as I love party on party action.
OP - I feel like you must have had terrible luck (especially during initiative) - as my experience was completely different. The encounter is 100% doable without any cheese or exploits. The intention here isn't too brag or disparage - but I must disagree with the claim that this fight is impossible without a lot of luck or exploits.
Yes, it's one of the tougher fights, but it's nowhere near as bad as described. For now, I think it's a very tough fight for a level 4 party with limited magical items (i.e. pre-goblin camp), and an easy to average fight for a 5th level party.
For clarity - the fight was done with a Level 4 party (Druid, Gale, Lae'zel, Shadowheart - pre-Goblin Camp) without the following:
- No pre-position (ran the chained party right into the conversation)
- No pre-buffing (outside of Aid, which is an always cast because it lasts forever)
- Did not use any psionic powers (fyi psionic pull will let you insta-yeet one of the Giths that teleport to the bridge for a likely instant kill)
- Did not use any 1-time consumables (i.e. haste potion, wyvern poison)
- Very limited magical items (mainly the Sword of Justice and Intellect Handband)
There was definitely some RNG involved (can't control it), and I did use height/backstab where I can (note, I did not start on high ground).
I'll do it a few more times to see if I was just incredibly lucky. Will record, upload and post them here.
