Is Temple + compatible with the Co8 extra content? I really enjoyed the Verbo stuff and going up to 20th level.
Yes, Temple+ is compatible with Co8 mods, and contains a bunch of fixes and other non-content additions (new races, new classes, new spells, new AI improvements and more).
I can get the new races under Temple but the prestige classes don't appear when I try and set up a character. I have ticked the box.
None of the prestige classes are available at first level. When a character chooses their second level and subsequently all prestige classes will be displayed with those for which the character meets the prerequisites being highlighted.
