Dharkstare

Dharkstare is the final boss of the Ice Ruins first appearing in. It is a dark version of Kholdstare who guards Sage Rosso's painting. Its lair is based at the bottom of the Ice Ruins.

Strategy
Like its Kholdstare, Dharkstare will encase himself in ice to protect itself. He is, however, capable of movement. He will attack by trying to ram into Link, and using three spinning orbs as projectiles, capable of freezing him. The latter will form a triangle after being thrown, and after a few seconds, anything inside the triangle will be frozen. In this form, its only weakness is the Fire Rod. After three hits, the ice barrier will melt, and it will flop around. Link must then attack it with his Sword. After a few hits, it will dissolve into shadows and reappear in the middle of the arena, where it will create a new barrier. After enough hits, its eye will become red, and will have six orbs spinning around him instead of three, meaning that he can create two trianges at the same time. Once he is defeated, Link will recieve a Heart Container and Rosso's Painting.

Trivia

 * Dharkstare is a portmanteau of the word 'dark' and 'stare'.
