Bone Javelins being thrown at a Target Dummy. Note how the damage over time increases once more javelins are attached.

The Bone Javelin is a consumable ranged weapon crafted from Sturdy Fossils. Upon hitting an enemy, it will stick to the enemy and inflict the Penetrated debuff, dealing 3 damage per second for 15 seconds. Up to six Bone Javelins can be stuck onto an enemy, dealing a total of 18 damage per second.

Notes

• Even though the base damage can be amplified with armor, accessories, and buffs, the continuous damage of one Bone Javelin will still be 3 damage per second.
• Bone Javelins appear to have a strange effect on Granite Golems. When the Granite Golem turns invincible by crossing its arms, all Bone Javelins will immediately disappear, but 1 damage will be dealt multiple times to the Granite Golem when the invincibility wears off. This is probably due to the damage over time being inflicted by having negative health regeneration, while the Granite Golem does not reset its regeneration stat immediately when turning invincible.

Tips

• The Bone Javelin is a great supporting weapon in pre-Hardmode boss fights, even after obtaining better weapons. Since 6 stacks are the maximum for the Penetrated debuff, landing 6 shots and changing to the main weapon with higher DPS will maximize the damage output.

Trivia

• The Penetrated debuff can never be applied to players, so it lacks a unique debuff icon. It uses the Distorted debuff's icon as placeholder.
• Bone Javelins act similar to a Daybreak which both stick to an enemy and inflict a stacking damage debuff.
