Hello,
I've just discovered Lost Crossroads yesderday and I am really interested in it.
Currently, I have chosen Spell Revisions as a required mod. But while SR is very good, it doesn't add many spells and I understand Demivrgvs's choice.
However, a well-done spell's mod that add many spells is good to have. Diversity and choice are very important in a game.
I have done about 10 spellbooks in BG1 for wizards. Each of them has a kit and because I follow PnP school opposition, I obtain different spellbooks.
But, due to tiny spells selection within a school at a spell level, I end up with similar spellbooks no matter what I do.
Well, at least, most kits are appealing with SR, it was not the case with vanilla spells. But I want more...
Not sure what I will get with Lost Crossroads, but I will test it a lot to see if it can replace Spell Revision.
