Weapons with the Healing Boost weapon skill are enchanted with nature voodoo, allowing a pirate to restore his or her own health without drinking a tonic or having an ally heal them with a voodoo doll. Healing boost charges over time when the weapon is equipped.
To use Healing Boost, the weapon must be in the pirate's hand and be fully charged. Then, select the Healing ability by clicking on the icon. The level of the ability will determine how much health is restored. It does NOT affect voodoo power.
