- "A walking volcanic creature fueled by boiling magma. Settler's reports indicate that Magmagrocks are born from its volcanic crater."
Vulcangrocks attack much like Bossgrocks and Diregrocks do, utilizing the same head-smash and body-slam attacks. Instead of summoning Footgrocks or similar grocks, Vulcangrocks will spawn Magmagrocks instead when they body-slam. Vulcangrocks also throw a new attack into the mix: erupting like a volcano and spouting flaming rocks everywhere. This attack can be devastating, injuring Dillon possibly up to several times and preventing him from getting near the grock. Even in Arma-Mode, these rocks can prove to be tricky obstacles for Dillon in reaching the grock. The attack can be predicted when the Vulcangrock's mouth begins to spout small flames.
A new move for the Vulcangrock was introduced in Dillon's Rolling Western: The Last Ranger, firing large fiery projectiles. It will rarely do that but it will make it more obstacles for Dillon.
Vulcangrocks have a monstrous defense, difficult to defeat with even with the strongest gear and sometimes even Arma-Mode. In the event the player connects a grinding attack, the move can chain to 100+, giving lots of rewards, but while damaging the Spikes heavily.
