The Netherworld Hospital is an important service in the game, as your characters will get injured in battle, and might even die. Whenever you reappear in Laharl's Castle in between battles, you can use the hospital to revive and heal your characters' HP and SP back to full for a small price. The formula for the cost of healing is as follows:
- HP - (Amount of HP/3)
- SP - (Amount of SP * 2)
- Revive - Cost of HP + Cost of SP + (Level of character * 30)
The best thing about the Hospital is that there is a rewards system for using it. As you reach certain thresholds for total HP and SP healed, as well as revives, you will be eligible for prizes. Note that these prizes are predetermined and will ALWAYS be set at Legendary rarity. The following table will list all of the items you can get, as well as when the thresholds are.
