Nobody said that soloing with a fighter is a cakewalk. Just that it's possible.
Anyway, I disagree that SCS2 "properly balances" the game. It just makes the NPCs use the same cheese the player can use. And that typically results in running in circles drinking healing potions for the first 12 combat rounds, when the enemy mages are 100% undispellable and invulnerable and waiting until their spells ran dry.
How many mages do nothing but renew their protective spells all the time? Even with SCS2 (where mages have more protective spells memorized, a lot of them in contingiencies, triggers etc) there's a timeframe between when the spell runs out and the AI decides to recast it.Maybe you're right and the game does let you kill liches with relative ease with Azuredge (or Imp. Mace of Disruption), no matter what they do. Pretty sure PfMW can be cast without a time of vulnerability though, with its zero casting time. There's a ton of other enemies that are immune to normal weapons though and cast PfMW - rakshasas, vampires, demons, IIRC some mindflayer too plus certainly something I'm forgetting. Plus Absolute Immunity cast by anyone, even if it's not as renewable.stuff
With very few exceptions like demi liches you can kite any encounter with boots of speed, jugging a potion every 6 seconds (without losing your attacks per round). Save-Or-Die? First, when you solo you'll get loads of XP so your saves will soon be in the negative. Second, Potions of Invulnerability, which give AC 0 and - 5 on saves cummulatively.It's not the melee'ers only problem that you can't always hit people, though. A lot of times enemies just deal much more DPS than you can heal with potions - and that you're often vulnerable to save-or-die stuff, and often have to rely on rare potions, scrolls or PW: reload to survive. When you're a single target with a very limited set of protection spells, surviving all the shit thrown at you is not so simple with just the DPS and HP of a single character.
Potions which give fire resistance (cummulatively), magic resistance, magic shielding, immunity to all spells up to lvl5 etc etc. green protection scrolls at temples usable by anyone. Potions of Invisibility. A cloak that reflects spells.did look up some info, the vanilla game indeed has been solo'd by a barbarian at least. Now when using even a moderate SCS2 install, and a less magic-resistant melee class than that, I don't see anyone doing a playthrough unless exploiting the AI in the lamest way or relying on tons of reloads and dumb luck. And to me a properly balanced BG2 install is always more relevant when game design is discussed, than the vanilla.
