This thread contains all verified rules errata from the Tome of Horrors. It is a closed thread, but I can open it to change and update the information here.
For the purposes of this errata, only rules-based errors are included. We are aware of certain spelling errors and they will, of coursed, be addressed in future revisions.
I have very few 1e and 2e resources at my disposal, so I have no way of verifying Credits or Copyright information. That errata will be taken care of elsewhere.
If you find any other rules errata, let me know in the other Tome of Horrors errata thread and I will update this one. Thanks!
