Celestial Stone

The Celestial Stone is a post-Plantera Hardmode accessory crafted from a Sun Stone and Moon Stone at the Tinkerer's Workshop. It offers the same boosts as its components do, and as such, it is active during both day and night. Stat boosts:
 * +10% melee speed
 * +10% damage
 * +2% critical strike chance
 * +2 HP/s life regeneration
 * +4 defense
 * +15% pickaxe speed
 * +50% minion knockback

Tips

 * In the console version, it is possible to get the Celestial Stone pre-Plantera. You can use the Rod of Discord to teleport into the Lihzahrd Temple, or blow up the door with a Bomb, allowing collection of both the Moon Stone and the Sun Stone. This cannot be done on PC, as the Golem cannot be summoned until Plantera is defeated (as of 1.2.3).

Trivia

 * The Celestial Stone does not show when equipped, despite the fact that its ingredients do.
 * Of the accessories, the Ankh Shield and the Celestial Stone give the second most base defense, being bested only by the Paladin's Shield which has 6 base defense.
