If you had more characters than the amount of slots you had access to, buying slots is what you need to do to access those characters. If you're at 12 slots accessible, but can't access characters, you need to delete a character to free up a locked one. If you can't do that, then you're character is screwed.

Vanilla 5e
The only thing I added outside of the PHB was 2 Cleric domains to balance it out statistically by the builds.
There are three builds in here for clerics, dex, wis, and str-focused. Each has 3 domains inside of it that are possible.
I added death and arcana to make it so all had 3 each, so it was statistically as likely to get any of them.
Other than those two domains, everything in this generator is vanilla 5e.
