Modify core data?

[Xykal]

I have added a domain using the editor and I would like to edit a few core spells to tie them to the domain. Can I modify the actual core data? Or do I have to add a copied / modified version of the spell using the editor?

You can modify the core data but i wouldnt recommend it. If you make a mistake there is no way to roll back from it. You should either create a test platform for the game or just create a file with the new information in it. That way its all kept seperate.

Chiefweasel, that's incorrect. The core data is protected and cannot be modified. Using the editor, you can replace the spell in question, but if you remove the file with the replacement, the original will be in use again.

Although it would work to make a replacement for that spell, I recommend making a new copy of the spell, and not replacing it, because you might end up sharing data with someone else. If you do share data, and they've also made a replacement for that spell, HL will see that the same thing is being replaced twice, and throw up an error, since it doesn't know which replacement to use.

Instead, make a copy of that spell in the editor, remove all the other classes/domains that have access to the copy, and assign your copy only to the new domain.

Sorry about that, I thought that you could change the SRD files, maybe I am thinking of d20 though. I havent created much for PF yet so i am most likely mistaken.
