Mana Booster

A Mana Booster is similar to a Mana Star, as it is consumed upon pickup, but instead immediately provides the player with an increased mana regeneration rate for 8 seconds. Unlike other sources of mana regeneration, the regeneration provided by the Mana Booster is independent of current mana supply or consumption, and will work even while continuously using a magic weapon. It can be dropped by an enemy when the player has a full set of Nebula armor equipped.
