Celestial Cuffs

Celestial Cuffs are an accessory that increases pickup range for mana stars and restores mana when the wearer is damaged. The mana restored from damage due to these cuffs will NOT stack with the mana restored from damage due to the Magic Cuffs

Like the Celestial Magnet, it increases the pickup range of mana stars by 20 blocks, for a total of 22 blocks. This effect does not stack with the pickup effects of the Celestial Magnet or the Celestial Emblem.

Tips

 * The Celestial Cuffs work even better with the Spectre Armor than the Magic Cuffs alone, because this combination will restore your mana when damaged AND will furthermore help you collect stars, allowing you to attack more often and thus heal yourself more effectively. Players are able to survive Hardmode Events a lot more easily with those items equipped.
 * The Band of Regeneration is found in Chests in the Underground and the Cavern. The Band of Starpower has a 20% chance of dropping from Shadow Orbs. Combine the Band of Regeneration with the Band of Starpower at a Tinkerer's Workshop to make the Mana Regeneration Band. A Shackle is a 2% drop chance from Zombies, and is combined with the Mana Regeneration Band to get Magic Cuffs. Finally, the Celestial Magnet is sold from the Traveling Merchant, and is combined with the Magic Cuffs to make the Celestial Cuffs.
 * Using Celestial Cuffs instead of Magic Cuffs will remove the 20 additional maximum mana you get from the Band of Starpower. This won't be a huge deal as you will very easily get mana back, but if you still prefer the 20 mana, the arcane modifier can accomplish this.
 * Having a dart trap in your arena rigged to shoot you will give you back mana if you lack in mana potions. Note that the dart itself may not do much damage, but that spamming the dart trap will slowly kill you, not only from the [small] base damage but also due to the poison if you lack a Bezoar or other accessory that can negate poison.
 * Spikes or Wooden Spikes can also accomplish this, without the risk of poison.
