First time poster but have been lurking for years. I am playing through BGII/TOB for the 5,000th time as a solo sorcerer. I frequently read BG sorcerer threads and guides at various internet locations and see the same thing repeated over and over again. I've finally had enough and want to throw in my 2 cents, so here it is:
Dispel Magic is good for a solo sorcerer and Remove Magic is not so good. There....I said it!! Why? Because you can cast Project Image/Alacrity/Time Stop/unload spellbook in a few seconds THEN have the image walk a safe distance from your incapacitated sorcerer and cast Dispel Magic on itself. It dispels itself every time and gives you back control of your character (you can then proceed to cast another Project Image and repeat the process if anything is still standing). The best part is you don't have to stand around waiting for your image to unsummon.
If you accidentally dispel your own buffs, so what? Everything is probably dead after the insane nuking you just administered.
I don't know how solo sorcerers that choose Remove Magic instead can stand it.
