The Opal Striker is a craftable Pre-Hardmode ranged weapon that does not consume ammo. While holding, the player channels a glowing orange orb at the tip of the gun which reaches its maximum power after 1.47 seconds. Releasing while fully charged discharges a charged bolt which deals 500% damage and 300% knockback, as well as piercing twice. Releasing while not fully charged fires a normal heated bolt which only pierces once. The bolts inflict the On Fire! debuff.

Its best modifier is Unreal.
