Peril Beam

The Peril Beam was a sword technique from The Legend of Zelda: The Minish Cap. Link learned this move from Waveblade, who was located in a tree by Lake Hylia, and could only be accessed when Link had acquired the Flippers. the Peril Beam was like the Sword Beam, only instead of firing when Link's health was full, it fired when he had only one heart left.
