Magic Cuffs

The Magic Cuffs are a pre-Hardmode accessory which increases maximum mana by 20 and restores mana when the wearer is damaged.

Mana restored is equal to the damage of the attack before factoring defense, but will never be lower than 10. Damage from drowning and debuffs does not trigger this effect, while damage from falling will. This effect does not stack with the mana restoration effect of the Celestial Cuffs.

Tips

 * The Magic Cuffs are a very valuable accessory when regularly using any kind of magic weapon. The maximum mana bonus can even be doubled by reforging the accessory to an Arcane modifier.
 * Self-inducing damage proves to be a reliable source of mana restoration. With a reasonable amount of defense, the damage taken can be reduced to a negligible amount, while the mana restored equals the base damage. Damage can be self-induced by, for example, traps (including Spikes and Wooden Spikes), explosives, or Explosive Bullets.
 * In comparison to the Mana Flower, the Magic Cuffs may be preferred due to the Mana Sickness debuff which consuming Mana Potions causes.
 * The Spectre armor set boost pairs well with this, as using a magic weapon costs mana and restores health, and when you take damage the mana is restored, causing the process to repeat as long as you aren't taking too much damage and dealing magic damage.
