Orin (humanoid) vs 4 Fighters level 10, BG3 Honour mode, no consumable/tadpole

Failed Hold Person, but thanks to Action Surge, it was still possible to down Orin on 1st round.
(as Dark Urge, I chose to interrupt the duel with my companions - as always I prefer a team fight.)
0:00 - Video starts
1:19 - Fight starts
4:33 - Orin killed in 1st round.
Durge San: Fey Warlock 3 / Eldritch Knight 7 (planned Fey Tome Warlock 5 / Eldritch Knight 7)

The party will be 90% Fighter at level 12. It is currently 93% Fighter.
Level 10, day 7.
ps. Haste on Astarion came from Lae'zel's Darkfire Shortbow. I don't know what made me decide to pre-cast before combat but here we are.
