This pyromancy periodically heals anything that comes close to it, including invaders, enemies and bosses. It heals moderate amounts of HP at regular intervals of approximately 3 seconds, and lasts for 90 seconds. As such, this is immensely useful for pure pyromancy builds due to the staying power it grants, though it needs to be used with some caution to prevent enemies from benefiting from it.
This spell can be very useful in PvP, especially as an invader who has limited options for healing. Assuming that the host does not have a Seed of a Tree of Giants active, Warmth can also be used to heal powerful enemies, as well as other invaders.
