The Xeno Staff is a Hardmode summon weapon. It summons a UFO minion that teleports to nearby enemies and fires lasers at them. The UFO is capable of moving through blocks. It is dropped by the Martian Saucer during the Martian Madness event.
Its best Modifier is Ruthless. The Mythical modifier provides the widest array of stats bonuses, but these primarily affect the initial summon rather than the resulting minion. Additionally, Minions cannot deal critical hits. The only significant advantage a Mythical Xeno Staff has over a Ruthless one is knockback.
- Despite having lower damage than the Tempest Staff, the summoned UFO attacks at about twice the speed as Sharknados. Its attacks also never miss.
