Elemental Skull

Elemental Skull is a high-tier undead which can be summoned by using [Summon Undead: 10th].

Appearance
A floating skull, surrounded by a magical aura that constantly changes its color between red, blue, green, and yellow.

Abilities
The Elemental Skull is a level 68 undead who has control over the four main elements.

Similar to a magic caster, its HP is far lower than that of the Doom Lord. However, its magical capabilities are not to be underestimated, because every spell the Elemental Skull uses is boosted with [Maximize Magic].

In terms of its defenses, the Elemental Skull has high magical resistances and has the ability to negate fire, lightning, acid, ice, and other types of elemental attacks. However, it is very weak to physical attacks, especially those that deal strike/bludgeoning damage.

Active

 * Polar Claw: A 9th Tier Spell, slashing attack with a floating claw that emits an ice-cold aura of the North Pole. This attack has no additional effect but boasts having the most damage of all ice element spells.
 * Seven Trumpeter: A 10th Tier Divine Spell
 * Vermilion Nova: A 9th tier spell. It is an attack targeting the opponent with a pillar of flame while dealing fire-based type of damage
 * Mist of Super Acid: A 10th Tier Spell that engulfs the target in acid steam and damaging target along with anything it has equipped.

Trivia

 * Pandora's Actor, under the form of his creator Ainz Ooal Gown, summoned an Elemental Skull during its fight with Platinum Dragon Lord's Armor.
 * However as stated by Ainz Ooal Gown and his Floor Guardians, Pandora's Actor's Elemental Skull was considerably weaker in comparison to the ones Ainz's can summon due to him not using Ainz's unique skills to enhance its power during his duel against Riku.
