The Piety Prayer gives a temporary 20% boost to a player's Attack skill, 25% boost to a player's Defence, and 23% boost to a player's Melee damage dealt. This prayer is commonly used while fighting bosses or another player to maximise the amount of damage inflicted.
Piety used to be the strongest stat-boosting prayer in RuneScape, but was surpassed by the Turmoil curse from the Ancient Curses: Turmoil increases stats by 10% while Piety increases by 8%. Turmoil also drains Prayer points at a faster rate than Piety.
To gain access to this prayer, players must complete the quest King's Ransom and the Knight Waves Training Grounds miniquest, along with having level 70 Defence and 70 Prayer. Piety is also needed to complete one of the hard Seers' Village Tasks. Boosts cannot be used to complete this task.
This prayer also has a role in the quest Nomad's Requiem, where it is the only way to stop the smoke from harming the player in one of the puzzle rooms.
