Stone tower temple was much harder for me since it took me ages to complete and I dont mean a few hours I mean probs days. The water temple was annoying but I completed that temple within an hour or 2. None are as hard as the goron dungion on the moon with that realy narrow path and you have to roll. untill I found out you can just aim strait and the chests line you up lol.
Well heres a small tip to those who havent competed the temples in
MM and want to get those stray fairies.
First off dont focus getting the fairies while trying to beat the temples 1st time, simply beat the temple like normal and once you done that you are free to take as much time as you need (within the 3 days of caurse *slow down time song recommended*) to collect the fairies plus you may have a usefull item after beating the temple that may help you out.
The stone tower and snow head fairies give the best rewards which are listed
Woodfall:
Stronger Spin Attack
Snowhead:
Double Magic Bar
Great Bay:
Better Defence (take half as much damage)
Stone Tower:
The Great Fairy's Sword
I am aware most people will know these but the help is here if anyone needs it.
