The Viral Sprout is a craftable Hardmode summon weapon. When used, it summons a flower-shaped spirit that floats around the player and attacks nearby enemies by firing gravity-affected needles. When moving or attacking, the spirits will move in a group with individual circular motions, and launch an even spread of three needles upwards. Needles inflict the Sage Poison debuff which deals a constant 45 damage per second, with higher damage per tick the more spirits are present.

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 Viral Sprout has over a Ruthless one is knockback.

  • The amount of damage in one tick equals to the following: 20 * (Minion count 0.73 + Minion count 1.1), rounded down
    • For example, if the player had 8 spirits when the item was applied, the resulting base damage would be 288. 20 * (80.73 + 81.1) = 288.24, rounded down.
