Now that the new domains are in, I have a couple of clerics (that arent level1) that would suit a different selection of domains than the ones I selected initially (pre-new domains)

Is it possible to have a conversation character somewhere you can talk to , to CHANGE your domains? of course this should only happen ONCE (since the new domains are in, unless new domains get added later) so maybe it should require a d.m given token in the characters inventory to make it work.

Or is it a LETO like edition that's too much hassle? If so thats fine i'll live with it.

It would be done using LETO.

I thought at one point that I had rescripted a part of LETO to properly handle the new domains, but now it seems to corrupt whatever character files I use it on, so I'm not entirely sure whether it can be used to switch people over to the new domains.
