Blasting Staff

Blasting Staff (ブラスティングスタッフ) is a type of staff weapon from YGGDRASIL

Description
It appears to be a weapon used by "Ainz Ooal Gown" during his battle with Tsaindorcus Vaision.

Appearance
It has the same basic appearance of a staff. In the anime the top of the staff resembles the head of a hammer with gems embedded in to.

Abilities
The Blasting Staff had an enhanced knockback enchantment. The cost of that enchantment was the staff’s complete lack of offensive capabilities, but it granted distance between a magic caster and their foe, one of the most important things to a caster.

The staff’s knockback effect had all kinds of activation conditions placed upon it, however, blocking a warrior’s strike with the staff would not trigger the effect. The effect would not trigger at all if the staff was not used offensively. If an opponent blocked the attacker’s blow with a sword or shield, its effect would not trigger. It would only trigger if one were to land a blow on their opponents’ body with it. A sword or shield would obviously not count as an opponent’s body. However, the effect would still trigger if one were to strike an opponent’s gauntlet.

Trivia

 * The staff's abilities was similar as Yamaiko’s Female Sensei's Iron Fist of Wrath save that it lacked offensive abilities.
 * During Ainz Ooal Gown's duel with Riku Aganeia, the latter's weapons caused the knockback effect. 'Ainz' had two possible theories:
 * That Riku’s weapons were creatures like Entoma’s Blade Bugs and thus alive.
 * That the weapons were not equipment at all but were actual parts of Riku’s body. Given the evidence, this theory seemed to be more likely.
