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.
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.
Yeah, in that room with the dual spike walls that will close in on your, you absolutely need Din's or else you lose a heart. Fire Arrows won't work, IIRC they just go through the wall or stick to the wall like a regular arrow does. It may be different for other versions but for V2.0, you definitely need Din's.You need dins fire to burn the spike wall leading to the big key in the shadow temple.
