Actually, in N64 Din's Fire isn't necessary. So, yeah. 3DS version, from what I know it is.
I could pull it off, in fact, I have before. It took forever. But, I didn't have 0 deaths. I can assure that.
You don't need to take any damage at all in the Water Temple, but the Zora Tunic is necessary for 3 hearts. Well, not if you Navi/Spell/Bottle dive. It can be done, I've seen it, youtube it.
This challenge requires glitches, and I don't believe you want that. I recommend more possible restrictions.
3 Hearts
MQ (3DS if applicable)
No Magic (excluding Din's)
1 Bottle (Ruto's, nothing in it other than fish/blue fire)
Broken Giant's Knife ASAP
No Z/L targeting
Skip shields/burn Deku shield (Only allowable is Mirror Shield for Twinrova)
No Deku Nuts or Deku Sticks (only sticks for the torches) <sticks do 8 dmg (same as biggoron sword) when used in jump attack>
No Lens of Truth
No Fire Arrows (No, they are not necessary, use a bombchu in the Shadow Temple, look it up on Youtube)
I've done that route. Really fun.
