Skeletal Dragon

Skeletal Dragon (スケリトル・ドラゴン) is a powerful undead being that mimics the shape of a dragon and is capable of destroying a city.

Appearance
The Skeletal Dragon is composed of countless human bones with an overall height up to three meters tall. Formed from bones with a rib cage devoid of organs and flesh, it looks rather light despite its large frame. Its head has four hollow eye sockets with a crimson glow in each of them. Possessing a jaw lined with sharp teeth, a long neck, a pair of bat-like wings and four legs.

Abilities
Aside from its massive strength, the Skeletal Dragon's specialty relies on its ability to nullify magic that ranges up to the 6th-tier. Therefore, this dragon's ability makes it the worst opponent for some magic casters. In particular, the low-level magic casters who used spells lower than the seventh tier are the ones helpless against it.
