Thought I would write a bit more about the Spellcaster-heavy playthrough.
First off, the MC, Fey Bloodline Overwhelming Mage Archetype Sorceress very similar to my Kingmaker play-thorugh, except Half-Elf for starting with 21 Charisma
Half-Elf gives access to additional feats, one for +1DC to Enchantment and one for +2 Spell Pen. Couple that with Demon Path for more DC boosts, and Free Action AoE Save debuffing soon.
Main things are super high DC Confusion and enough single target paralysing spells to render an endless series of non-immune targets helpless. She has Red Salamander ring so that she is not entirely useless when no spells work and a Spellbook half-filled with joke spells which only have very specific places where they are useful - Hold Person anyone? Hilariously OP when enemies are vulnerable, weakest party member when not. Has a sideline in hitting things ineffectively with a huge Greatsword. Eventually going to be Abjuration Pro too for cracking open Freedom of Movement.

Daeran is an AoE monster now that he has Flame-strike. I love that Spell. He is basically going all in on Evocation. Key things are Archon's Aura and AoE Evocation, and Skeletons, lots and lots of skeletons. Maximised Skeletons. Sideline in spamming Arrow of Law.

Camellia She has little spellcasting offensive power. She does a bit of everything but is primarily a Summoner/Dead Animator, with enough Summons/Skeletons and to choke up the entire battlefield - she also carries plenty of buffs to supplement Daeran. She also represents most of the parties Melee power so tends to sweep up stuff when necessary. Also I have her on Evil Eye duty - She does far more than Ember can: Summons, Debuffs, Melee, Buffs, the whole works, but lacks any sort of specialism and no offensive spells. Has the highest AC of anyone but mostly hangs at the back and most things that take a swing at her only get one chance before they get Constricting Coiled.
Mythics: Abundant Casting, Sorcerous Reflex, Greater Abundant Casting.
Nenio The second half of the Will Save Crushing Duo. Nothing holds up to Phantasmal Putrefaction and Phantasmal Web - and Phantasmal Putrefaction debuffs Wisdom meaning the next salvo of spells hits even harder. Once she gets Sorcerous Reflex nothing will stop us.
