by secret ending.)...or you can get 74 dc on spells...
I was thinking the upper limit somewhere around 50. There must be some insane items in this game. Tell me more. Is it possible to learn this power?
20 Overwhelming Mage, 16 Vivisectionist, 2 Paladin, 1 Scaled fist, 1 Enlightened Philosopher, legend path
Start kindred raised so you can start with 22 cha, you'll want to max out your cha as much as possible with cognatogen and profane ascension from Nocticula and conflagrent taco from Iz. You can't have profane ascension AND legend until you're in the final dungeon, also she gives you a +8 cha headband in the final dungeon so that's 74 dc, 70 in act 4. Max cha I've gotten is a +26 mod so that's +26 dc in act 6.
You'll also need to use the expanded illusion exploit, take spell focus and greater spell focus in every school except the school you wish to use, then use expanded arsenal into the school you want as your 1 and only mythic feat. That gives +14 dc
Base: 10
Cha: +26
Expanded arsenal: +14
Spell level: +9
Magicians ring: +2 (you get 2 of these from crusade battles, there's also 1 in a map with no quests.)
Quarterstaff of the war mage: +2 (ivory labyrinth loot)
Glass amulet of clarity: +2 (Gift from Vellexia.)
Robe of determination: +2 (I forget where i found it sorry :<)
Demongraft: +2 (From the doctor in battlebliss)
Overwhelming spell: +3
School power illusion: +2
74, without expanded arsenal exploit it's 63. Reason there's scaled fish, enlightened philosopher, and paladin is to get cha to ac and saves. Scaled fist + enlightened philosopher + paladin smite ac all add up so you can get 3x cha to ac, which means 78 ac from cha alone. If you choose the evil option in Daerans final quest you can get a permanent version of the paladins deflection ac cha bonus so there's no need to use smite for it too. Should be well over 100 ac lategame with buffs and spamming 74 dc weird. Nature oracle replaces dex to ac with cha to ac so just dump dex.
The cha is 22 base, +8 cognatogen, + 10 from asis, +4 legend, +6 profane ascension, +8 headband, +4 taco from Iz = 62 (26 mod)
