The Xeno Staff is a Hardmode, post-Golem summon weapon that spawns a UFO minion that instantly teleports above the nearest enemy before rapidly firing thin blue lasers at its target. The UFO's lasers are fired instantaneously at a rate of once every 0.4 seconds[1] on average. If the UFO minion is more than 75 tiles away from the player, it ceases to attack enemies and returns to the player.[2] The Xeno Staff has a 16.67*1/6 (16.67%) chance of being dropped by the Martian Saucer during the Martian Madness event.
Its best modifier is Ruthless. The Mythical modifier provides the widest array of stat bonuses, but these primarily affect the initial summon rather than the resulting minion. Additionally, minions cannot deal critical hits. The only lasting advantage a Mythical Xeno Staff has over a Ruthless one is knockback.
Tips
- Despite having lower damage than the Tempest Staff, the UFO is superior to Sharknados regarding attack speed and accuracy. However, it cannot attack in all directions like the Sharknados. This is usually a problem in tight spaces but not when in open spaces.
Trivia
- Prior to the 1.3.5 update, the Xeno Staff had an extremely low sell value, making reforging it to a desired modifier very cheap.

. The UFO's ai[1] is increased by 1 each tick and then has a 2/3 chance to be increased by 1 another time. Therefore, it is increased by 5/3 on average each tick. The threshold is 40, so the average cooldown between attacks is 40/(5/3)=24 ticks - ↑ Information taken from the
