Adding a Domain to Channeler of the Unknown

[Andrew]

The Channeler of the Unkown archetype has a restricted list of domains. For my current campaign I want to add one to the list . I think I have found out how to do so but I cannot copy the archetype and produce a new version with the extra domain.
At the moment I can see 2 options
1)Manually copy the entire archetype into a new one , and then add the new domain
2) Overwrite the Destruction domain with the new one I have created , but this will change the domain for all characters .

As all I want to do is add one item to a list number 1 adds a lot of work , and number 2 looks dangerous.

The change I have made is to change the spells granted by the destruction domain at levels 3 and 8 as for this specific character 2 other options seemed more appropriate

I dont see an adjustment for adding a spell to the domain list, but you might look at the domains and see who they do it, and possibly recreate that functionality via an adjustment.

Sorry I was not clear.
I can change the spells in a domain creating a new domain (Gyre) based off destruction. Unfortunatly the Archetype has a list of possible domains which I cannot find a way to edit without manually copying the entire domain over.

The new domain is available to normal clerics but not on the short list for the archetype

Try adding the SpecSource tag for that archetype to your new domain?

Thanks that may have done it.

I cannot add Gyre domain to the short list for the channeler of the unknown archetype, but If I add it to the character from the general cleric domain list and then give the character the archetype then it accepts it without an error message.
That will do as a work around
