Ultime-Volcano Mountain Trail

Ultime-Volcano Mountain Trail (ユルティム火山 登山道) is a fiery Grand Magic Zone.

Description
A large concentration of mana deep underground keeps the volcano constantly erupting. The high temperature, together with the uncontrolled atmospheric mana, also makes the surrounding air difficult to breathe, giving the sensation that the throat and chest are burning. Because of this, spells like Mana Skin are needed to explore the region.

At night, the volcano stops erupting and the lava recedes. Heated water then bubbles out of the volcanic vent, turning the crater into a large hot spring.

Beneath the region is a network of caves that leads to the underground mass of superheated mana that fuels the volcanoes. These tunnels are even hotter than the surface, so they serve as a more extreme training ground. Hidden within the caves is a dungeon.

Wild Life
The mana also gives rise to magical lifeforms made of lava. The creature Borula attacks a group of Magic Knights training in the area and creature manages to block their way until Asta's One-Horn Bull Thrust pierces through it.

A monstrously large spider invades the underground caves and kills off most of the native creatures that dwell in the caves.
