okay
Right. And that was my original argument for not including an immunity to Sunder. Either your DM doesn't use Sunder, or if he does, you should change your playstyle to be prepared for it, instead of relying on your class to protect you.No; he can easily have a backup. It wouldn't be enchanted, so it's not something he'd want to use long-term, but just until he gets a chance to fix his main one it could be ok.
