Wizards are normally my favourite class, but INT is useless outside of being their DC stat in this game.
Sorcs are just OP - I made a mistake though of taking the spell crit feat at level 8 instead of ignore poison resistance.
However people saying that humans are weak, I just found a reason for them towards the end of Act 2. The big bad boss drops a +1 spell DC shield. Non human casters lack shield proficiency and I can't change my race, but its ok for now as I can pass it to Wyll or Jaheira.
I recruited Jaheria so was forced to use her for the mind flayer pit, and found out druids are actually good for spellcasters. No fireball but call lightning and moon beam are ok, the problem is all their good attack spells are concentration based so you can only use 1 at a time. I plopped down two level 5 slot firewalls on the Mrykyl boss and he just melted.
But now I need to find a dead animal to raise into a spore thing. I made Jaheira a spore druid mainly for double cloudkill, and halsim a moon one.
I have the acid arrow staff on my sorc still and poisoner robe, gloves and cape. which removes two +1 DC items in the chest and gloves slots, but I handed them to Jaheira instead of using medium armour and the +1 ranged spell DC fire staff and +1 DC shield. Mega double firewalls or cloudkills. Also the fireball staff adds fire bolt cantrip, and it works off Wisdom instead of Int for Jaheira, plus the elemental infusion ring so +1d4 fire damage on top of shillegah when not using spell slots.
Yep. I've been saying humans are no longer weak because of the Shield Proficiency, but I still don't like it because shield proficiency for humans and half-elves is not thematically appropriate, especially considering Dwarves don't get it. Wood Half-Elves are still better than humans because they get the Shield, too, but the 3 most popular races also happen to be the best for the 4 most popular classes (plus Wizard). I don't think that is a coincidence. In my opinion, you can achieve the best synergy of race and class with only 3 races: Wood Elf, Wood Half-Elf, and Half-Orc.
