I think allowing for these weapons to innately support their domain is a solid start in terms of making them more unique and effective for their intended purpose, especially with Burngada and Cerron Scepter, as those are two spell domains (Nerfian and Aquarian) that you can't get non-Will scaling casting tools for otherwise barring mutations (or the rather outdated Reaper/Apa racials).

For potential thematic and new build directions, I give this idea a thumbs up-
