Boosts the player's total HP in exchange for souls. Both the HP gained and the duration depend on the souls held by the cast at the time of casting: casting the spell with little to no souls results in a minute gain that lasts 30 seconds; alternatively, casting it with 2,000 souls results in a gain of about 20% of the player's total HP, which also lasts for 60 seconds. The effects of the spell can be combined with other items or equipment that boost the player's HP, such as the Life Ring variants.
