Magic Cuffs

Magic Cuf are an accessory that increases maximum mana by 20 and restores mana when damaged. Mana restored is equal to the damage of the attack before factoring armor, but will always be at least 7. Therefore, an attack that deals 7 damage while wearing 20 armor (thus having taken 10 points of damage negation) will restore 17 mana. Damage from drowning and Fire Blocks does not trigger this effect, while damage from falling will.

The Arcane modifier adds another 20 mana, totaling to 40 extra mana. Due to its effects, it can remain useful well into hardmode and is extremely valuable to magic players.

Tips

 * The Magic Cuffs work extremely well with the Spectre Armor, as damage will restore your mana, allowing you to attack more often and thus heal yourself as well as effectively converting damage input into health.
 * It works well in boss fights in general, as the constant damage input will keep your mana near-full, allowing you to continuously attack. One must monitor their health while doing so though, as mage-style players tend to have low defense. A Mana Flower might be preferred.
 * It is recommended when battling Hardmode enemies, due to their high damage output.

Trivia

 * This item might be a reference to Yu Yu Hakusho's spirit cuffs.
