This staff possesses the third highest damage per shot of any staff and the unique property of ignoring its target’s defense, at the cost of a massively reduced rate of fire. As such, it is most useful in situations where you would need to pack a lot of damage into single shots, or against enemies with very high DEF or the tendency to Armor themselves.

This staff outdamages the T12 Staff of the Cosmic Whole at 38/35 DEF, the T13 Staff of the Vital Unity at 53/48 DEF, and the T14 Staff of the Fundamental Core at 68/62 DEF.

Note that this staff has a lengthened range of 9 - tied with the Staff of the Crystal Serpent - making it a fine choice if you need extended range to snipe a boss from the range of a Wand user. It also has a significantly faster projectile speed and smaller amplitude than tiered staves, making it easier to aim with.

A relevant comparison would be to spellblades. This staff outdamages the T11 Spellblade of Starry Insight at 31/28 DEF, the T12 Spellblade of the Sun at 56/51 DEF, the T13 Spellblade of the Heavens Light at 76/69 DEF, and the T14 Spellblade of the Everlasting Death at 101/91 DEF. High-tier spellblades offer generally higher DPS and can partially pierce enemies, at the cost of having significantly shorter range and significantly slower projectile speed than the Tail.
