Mana Polarizer

The Mana Polarizer is a Pre-Hardmode, Expert Mode-exclusive accessory obtained from the Treasure Bag dropped by the Slime God. It increases the player's maximum mana by 50 and magic damage by 6%. Additionally, striking an enemy with a magic-type projectile will cause a short-lasting heal orb to spawn from an enemy. Upon contact with the player, the orb heals for 20% of the projectile's damage multiplied by the ratio of the player's current mana over their maximum mana. This healing will only work if the user is holding a magic weapon. The more the player is healed, the less often healing orbs are spawned from an enemy. However, the Mana Polarizer will reduce the player's life regeneration by 3 while its wearer is above 50% mana.
