Primary fire launches two slow moving green bolts that when hitting enemies deals a small amount of damage over time. High spread and mana usage, low damage, fast fire rate.
Secondary fire launches four bolts at more mana cost and slower fire rate.
This weapon excels at doing damage over time. You can poison an enemy with just one projectile, and it does enough tics of damage to take out most enemies. Because only one projectile is needed to cause the poison status you can clear entire rooms with very little mana. However, after you've poisoned the enemies you have to dodge their attacks until they die. This weapon is usually less effective against bosses because of their high HP.
