Blood Rush

Blood Rush requires a Magic level of 56 and can do a maximum of 15 damage per spell. If damage is inflicted on the opponent, the caster is healed for ¼ of the damage inflicted. The maximum amount you can heal with this spell is 4 hitpoints. As with all Ancient Magicks spells, the quest Desert Treasure must be completed to cast this spell.

Blood Rush costs coins for each cast.

This healing effect is best with soul split as 1/4 of the damage plus five hitpoints is healed maximum per spell
