Fighting Ansur & playing it extra safe (Act 3, Honour Mode) | Baldur's Gate 3

After rewatching the video I realised I could have done even better, but alas, a few mistakes were made. Also, don't be like me and examine / read about bosses you're fighting.
This is the only encounter in the entire run where I decided to hide one party member away from the action (and I am not ashamed to admit it). It ended up being an overkill, but I had issues dealing with Ansur in both previous playthroughs, so I was extra worried about TPK. In reality I barely took any damage & most of it was from friendly fire.
Though, that friendly fire from Nyrluna came in very handy causing the Volatile Shield to explode, stunning Ansur & getting me that Crash Landing trophy.
Astarion & Karlach carried the fight, my Bard was kinda just there. The party was at level 12: Astarion - 8 Open Hand Monk / 4 Rogue Thief, Karlach (TB thrower) - 5 Berserker Barbarian / 4 Rogue Thief / 3 Eldritch Knight Fighter, Dark Urge - 8 Swords Bard / 2 Fighter / 1 Wizard / 1 War Cleric.
Useful things anyone can bring to the fight: potion of lightning resistance, globe of invulnerability & any spell that inflicts blindness.
