Well, Fierce Deity Link is too fiercesome for me.
Not fearsome.
Besides, what's Link gonna do? Call the Ghostbusters? (Spirit Tracks Zelda would be sad.)
I don't have the Fierce Deity Mask yet, Bloom. Besides, getting the Couple's Mask has proven to be harder than thought. It doesn't help that on the Final Day, you have to complete Sakon's Hideout and that failure means you have
start the quest again. Getting all the masks will be worth it though...
