Lol. I like le spinner though I'm not sure Sera would like it. I mean, I'd be cool with any of the weapons really. I feel like the dominion rod is more Naria's style being 'Wisdom' and it's a scepter type thing.

They do each get a sword however. But the master sword will be found as one sword and then split into three for the sisters, balancing the power among them. Only together will the three swords have the power of the master sword's whole. 

They will each get a shield and the armor/clothing when it is given.

They will only get one of everything else and will have to share them items among themselves. So, say Sera gets the Gale Boomerang her being the spirit Farore, wind. But I also think that they should each get a set of iron boots so that they can travel together and not have to trade items underwater, yanno? So I think some items need to be duplicated for traveling purposes but others only come in the number they came in 'canon.'
