Bonfires act as checkpoints in the game world. While resting at a bonfire you may fast-travel to any previously lit bonfire, attune spells or access your storage box. The bonfire cannot be accessed when there are enemies nearby.
Resting at a bonfire has the following effects:
- Refills your HP, FP and Stamina
- Removes any status ailments
- Recharges your Estus Flask's uses
- Resets and respawns enemies (except unique enemies and bosses)
