1. Other than Shield spell, Stunning Barrier, Expeditious Retreat, Mirror Image, Shield spell, Sense Vitals, Mirror Image and Shield spell. Did I Mention Shield spell? Personal spells are a thing. Wolj can even get there as a Transmuter with the Hat that gives you Swift Hastes and Slows. Then there's endgame Hellfires.1. Which is exactly my point, Eldritch Scoundrel is a terrible hybrid class with no useful synergies between rogue and wizard.1. why else would you use your spell slots? if you want your rogue to play like a wizard, roll a wizard.Oh what a good fucking character who has to use up all of his spell slots so he can do what a regular ass rogue can do a lot sooner, not to mention that mirror image and blur are utterly useless against all bosses AND he still can only use daggers.
2. he doesn't do what a regular rogue does, he does it better. Archmage Armor gets you way more AC than a regular rogue could get, and regular rogues don't get access to defensive spells at all except through UMD.
3. since True Seeing doesn't work RAW in this game, Blur and Mirror Image *does* work against bosses and against regular mobs. unless you mean bosses that target saves and not AC in which case I don't see how ES is any worse than a regular rogue.
4. all characters can only use one weapon type if you're building them properly. there's great daggers in this game with on-hit debuffs and/or buffs on equip. damage dice is irrelevant since they're completely overshadowed by sneak attack and DEX mod bonuses. and anyways you get more finesse training soon enough that you can switch him to another weapon if you really want to.
2. Who gives a hoot about Archmage Armor, a regular high DEX rogue with the proper feats can have good AC as well, besides when your rogue is being targeted you're doing it wrong.
3. Let's pretend that's true, then there's still no reason for Eldritch Scoundrel to exist because any other old magic user can just cast blur etc. on any given rogue, you're only losing out on mirror image, which isn't that good anyway.
4. Wasting a level just to give him proficiency with better weapons (like kukris, of which there are much better ones than daggers) just so you have access to redundant self buffs is a bad deal.
2. ES can handle itself fine when targeted, but doesn't really need Archmage until late since it scales by Mythic Level. Losing Light Prof is significant given the good late Lights, you do have a point here.
3. see 1. The point that you can cover Wiz buffs for team with Scoundrel which frees up Wiz to cast offensive spells or leave Wiz home altogether, which is good early-midgame.
4. His weapons are fine already. Perfect place for Blitz Cut or Rapiers if you let Cam die, the Daggers are good anyway since Reducing/Sneaks/DEX-to-dam makes damage dice not matter. Retriever's Claw gives x3 crit multiplier and you get Blind on Crit early.
You're going to need a plan to Dispel things anyway so by the time True Seeing shows up you can use that (or Mind Blank now I guess). I just cast first round on hard fights then move in so don't get attacked much anyway.
Those few personal spells are of marginal use overall and not at all worth losing all the stuff rogue gets over eldritch scoundrel.
"The point that you can cover Wiz buffs for team with Scoundrel which frees up Wiz to cast offensive spells or leave Wiz home altogether, which is good early-midgame." Is there a reason why you don't buff pre encounter instead of mid encounter? Also why would you ever leave your mage at home unless your PC already is one?
"You're going to need a plan to Dispel things anyway" No I don't, I beat the game 3 times on core without dispelling much of anything except all that stuff on Areelu so I can hit her. Explain how it is a good gameplan to 1. cast a buff and then 2. rely on a dice roll so that buff even has an effect. Just use other buffs.
