Here’s the clean non-glitch way to beat Morpheel without Zora Armor in Twilight Princess : use the air-refill trick with Iron Boots and Water Bombs, then fight from close range and keep repeating the eye grab-and-slash cycle.

Phase 1

  • Start by using the Clawshot on the eye inside the tentacle, then finish that first form with a quick spin or strong combo.
  • If you need the faster setup for a no-Zora-Armor run, position yourself on solid ground with Iron Boots on, pull out a Water Bomb, then open the item wheel and unequip the boots right before the bomb appears.
  • When you return to control, hold forward and press the release button so the bomb triggers the air refill effect instead of exploding.

Phase 2

  • Swim up near Morpheel’s back eye, Clawshot onto it, and immediately hit it several times with your sword.
  • After a few hits, you’ll be shaken off, so repeat the same approach until it goes down.
  • Stay careful not to drift too far from the floor/solid reference point when using the refill trick, or the setup becomes harder to maintain.

Practical tips

  • Keep the Iron Boots ready for emergency positioning, especially if Morpheel starts its vacuum-style attack.
  • Don’t try to rush the second phase from the front; approaching from above and behind is much safer.
  • If your damage feels low, remember the eye needs repeated hits in phase 1 before the second phase fully opens up.

Simple method

  1. Get to the boss room and start the fight.
  2. Use the Clawshot on the first eye.
  3. Trigger the air refill trick if you’re avoiding Zora Armor.
  4. In phase 2, Clawshot the back eye.
  5. Slash repeatedly.
  6. Repeat until Morpheel is defeated.

That’s the standard no-glitch approach used in speedrun and guide discussions, and the key idea is simple: create enough air to stay in position, then keep attacking the eye until the fight cycles out.
