Life Stones are a character's free resurrections. Every character starts out with five of them and they are replenished at a fixed time every morning, which happens even if the character is currently dead in a dungeon. As long as a character has Life Stones, self-resurrecting in a dungeon consumes one even if there are Resurrection Scrolls remaining. The stock of five cannot currently be replenished apart from the daily reset, nor can the maximum number be increased.
Life Stones cannot be used to resurrect a party member. When a player revives a party member, a Resurrection Scroll is automatically used even if he or she still has Life Stones. There is currently no way to transfer Life Stones from one player to another.
