Hm. So there's even a flaw in that option. Although with someone as dangerous as Ganondorf, we may not need to worry about ever removing it.

[...Still] In case such a situation does come up, do you think removing it in the tunnels might help? Since the tunnels already hinder unnatural abilities with little negative effects, it could possibly lessen or null the side effects of the collar, if it was removed in the tunnels first, rather than in an area where our powers are normally allowed.
