Rock Octorok

Rock Octoroks are enemies in The Legend of Zelda: Breath of the Wild. They are a land dwelling variant of Octorok that live in volcanic mountains and have rocks on their head which they use as camouflage. Unlike other species of Octorok, they inhale air before spitting out a flaming rock. Unlike Forest Octoroks, Water Octoroks, and Snow Octoroks, they are invulnerable while hiding under ground and their rocks are impervious to damage or breaking. However they only hid if Link gets too close or sense an attack.

Like Dodongos, Link can throw a Remote Bomb in their mouth while they are sucking in air, then detonate it. Interestingly, Link can also throw weapons or shields in their mouth which they will spit out, which will damage Link if they spit out a weapon. While this may seem to serve no purpose, if Link throws a "Rusty" weapon or Rusty Shield into their mouth, they will chew it and spit out a better weapon or shield at random. In the case of weapons, its weapon type determines which random weapon of that type he will get. For example, Rusty Broadswords refresh into other single-handed swords and broadswords, while Rusty Claymores result in Claymores and other two-handed swords, and a Rusty Halberd will result in spears and polearms. Rusty Shields refresh into various shields, even wooden ones despite Rusty Shields being metallic shields, though Link must be careful when refreshing shields in the scorching temperatures of the Eldin region, as it can easy burn up the shields the Rock Octorok spits out, though Rock Octoroks due appear outside of these high temperature areas.

Additionally, there are two islands containing Rock Octoroks surrounded by Lava in the Eldin province. One appear on the island located between Goronbi River and Goronbi Lake while another can be found on the island in the northeast portion of Lake Darman. Near these islands are places where several "Rusty" weapons appear. These locations silently encourage one to throw the nearby "Rusty" weapons at them and serves as a way for Link to learn of this unique refreshing ability of Stone Octoroks. As a result, Link can use these islands with Rock Octoroks to turn them into the weak rusted weapons into stronger more valuable ones. Though Link generally receives "Traveler" series, "Soldier" series, "Knight" series, and rarely the "Royal" series. As a result, Link can obtain rare powerful weapons very early on this way.
