So I created a 4th level Wizard to join a campaign in progress; at 4th level a standard wizard knows 4 cantrips.  I chose School of Illusion, which gives me a bonus Minor Illusion, and as a High Elf, I get another bonus cantrip.  I have four cantrips in my spell list, but I can't add a 5th & 6th; the "learn" button is greyed out.  Am I doing something incorrectly or is this a limitation of the system?

The cantrip Minor Illusion from School of Illusion should be automatically added to your cantrip list.

The racial bonus cantrip can be selected from the Race page in the editor.

Thanks!

I see where I've gone wrong - I added Minor Illusion as the racial bonus; changing that allowed me to add a 5th cantrip.  So it looks like the racial cantrip doesn't show up under "prepared spells" but I can see it in a section below; if I choose Shocking Grasp, for example, it doesn't appear in the spell attacks section the same way as Firebolt or Chill Hand do from my spellbook.   Is there something else I need to do to have that work like the other spells, or is that just the way it's set up?

For now, it is just the way the sheet works.

The revamp should address these problems for racial spells.

Thanks for your help!
