The Dendrite Staff is a craftable Hardmodesummon weapon made from materials found in the Fractal Dimension. It summons a mini mandelbrot minion resembling a small Phantobrot, which will float over any nearby enemies and periodically shoot lasers down onto them. If more than one is summoned at once, they will alternate their shots, dealing damage in more rapid intervals instead of all attacking at once. Like other minions, the summoned mini mandelbrot is invincible and follows the player for an unlimited amount of time, unless the player dies, exits the world, summons a replacement minion, or cancels the buff.
Its best modifier is Ruthless. While Mythical provides the widest array of stat bonuses, these primarily affect the initial summon rather than the resulting minion. Additionally, minions cannot deal critical hits. The only lasting advantage mythical has over ruthless is knockback.
