Ethel Act 3 vs 4 Wizards level 10, BG3 Honour mode, no consumable/tadpole

It was again decided that Duelist's Prerogative will be part of the build, so Ethel had to be dealt with. I like the extra reaction combination with Sentinel feat.
Durge Fiat: Swords Bard 6 / Necromancer 4 (planned Swords Bard 6 / Necromancer 6)
Tav Paul: Tempest Cleric 1 / Great Old One Warlock 1 / Abjuration Wizard 8 (planned Tempest Cleric 1 / Great Old One Warlock 1 / Abjuration Wizard 10)
Gale: Tempest Cleric 2 / Evocation Wizard 8 (planned Tempest Cleric 2 / Evocation Wizard 10)
Shadowheart: Vengeance Paladin 6 / Divination Wizard 4 (planned Vengeance Paladin 6 / Divination Wizard 6)
The party will be 67% Wizard at level 12. It is currently 60% Wizard.
Level 10, day 8.
