Once repaired, Caladbolg will regain the magic you've outlined. We'd like to offer that Caladbolg can cleanse small areas (30ft radius) that have been tainted by the influence of the Death plane outside the barrier that surrounds the archipelago, which may come into play during future missions.

You are welcome to make an OOC post, which may be helpful for coordinating with other players. We look forward to seeing how the plot progresses!
