Gensokyo/Diamond Pendulum

The Diamond Pendulum is a Pre-Hardmode accessory available at the Curio Trader after defeating a Tier 1 Boss.

When ore, gems or chests are in a radius of 12 tiles around the player, the Diamond Pendulum will begin to emit a blue glow. The brightness of this effect increases as the player comes closer to the treasure.

Additionally, the Diamond Pendulum provides 2 defense.
