The Butterfly Staff is a craftable summon weapon. It summons 3 butterflies of random color, at the cost of 1 minion slot, that seek out and attack enemies near the summoner. Like other minions, summoned butterflies are invincible and follow the player for an unlimited amount of time, unless the player dies, summons a replacement minion, or cancels the buff.
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 significant advantage a Mythical Butterfly Staff has over a Ruthless one is knockback.
- The Butterfly Staff is considered one of the hardest weapons to craft in the Thorium Mod due to the extremely low spawn chance of the Gold Butterfly, which is 1/150 (0.67%).
- The Butterfly Staff has surprisingly high longevity, being viable even in Hard Mode; the fact it summons 3 butterflies per slot means the player can dish a surpsingly high amount of damage-per-second with proper max minion increases from armor and accessories. Its drawback is that the butterflies won't chase enemies offscreen and will mostly attack those near the player.
