Terraria

Yep, a typo.

While you're out digging through the world and doing your thing, you'll occasionally find red stone hearts called Crystal Hearts. Breaking them with a hammer will drop a Life Crystal, which will increase your maximum life by 20. The maximum amount of health is 400, or 20 hearts. These are most commonly found in the Dungeon and Underworld. You'll max out your health fairly quickly once you reach the Underworld.

For mana, you'll need to gather Fallen Stars, which naturally spawn at night on the surface. Collect 10 Fallen Stars and combine them to create a Mana Crystal, which you can then use to increase your maximum mana by 20. The maximum amount of mana is 200, or 10 stars. At night, Fallen Stars are plentiful, and if you set aside each night to collect them you'll quickly max out your mana.
