Elemental Infusions are consumed when you use a non-Melee Projectile Attack to Infuse the Projectiles fired by that Attack. Infused Projectiles trigger an Infused Blast when they reach the end of their flight.

Your weapon can have a maximum of 6 of each type of Infusion active by default. Infusions last 15 seconds. Infusions are specific to your current weapon, so do not affect non-weapon damage and are not carried over if you weapon swap.

Projectiles which Split or Fork from an Infused Projectile do not gain the benefits of Infusion.
