I played this GOG version about 10 years ago by using a balanced party. And now I have forgotten most of the content, so I think it's a good time to replay it. I'm considering soloing by using a wizard.

Someone suggests using melee weapon glaive, and I also saw such a gameplay video. But to me, I want to choose wizard to enjoy soloing as spellcaster, so I prefer my wizard to mainly use spells rather than melee weapons.

It seems that this GOG version adopted an old mod to fix bugs, remove level cap, add a few spells, ...., and I'm fine with that. I decide to go with this version and am not planning to install other mods.

I have heard that the Dominate Person and the Dominate Monster spells are overpowered in this game, so I won't use them and would only use Charm Person and Charm Monster.

If I'm soloing other D&D games, I don't mind using a crossbow to add a few attacks when my summoned monster is tanking enemies. And in rare situations, I'm even fine to cast close-combat buffs together with Tenser's Transformation on myself and confront a spell-immune boss by using a sword. But I need to know the exact arcane spell list of this GOG version to see if soloing as a spellcasting wizard is really viable even in rare situations like the aforementioned one. So is there a complete arcane spell list of this GOG version?

Besides, I'm would appreciate to learn any other advice for a solo wizard. For example, is the Toughness and the Improved Initiative feats worth taking? And since I would be likely to summon monsters often, is taking the Augment Summoning feat worthwhile?

Some feats are bugged in the vanilla game, like Improved Initiative. The Circle of Eight mod does a good job of fixing a lot of them, including this feat, but I have yet to test it since I always seem to have a better choice.

INstall the CO8 mod AND the Temple+ mod. You;ll have far greater stability, and a topn of additional content
