The Gladiator's Locket is a Pre-Hardmode accessory found in the Marble shrine. When equipped, two Sword Spirits will circle the player and will damage enemies that they contact. The swords orbit in opposite directions, at slightly different speeds. Each sword has a base damage of 20 and ignores enemy immunity frames. The swords deal classless damage, boosted by an average of each of the player's class damage bonuses.
Their base damage increases to 50 in Hardmode, 100 after Plantera has been defeated, 200 after the Moon Lord has been defeated, and 300 after The Devourer of Gods has been defeated. Their orbiting speed also increases after each of these milestones, traveling over 3 times as fast after The Devourer of Gods is defeated compared to its original speed. On top of that, the swords deal damage at faster rates, ignoring more enemy i-frames, after each milestone.
