Guardian Angel (Tier 2) detail

Guardian Angel (Tier 2) can be obtained from the Zamorakian quartermaster or the Saradominist quartermaster during the Battle of Lumbridge for 60 Renown. A player can "Drink" this item and then the next three attacks they receive during battle will only be a single point of damage, if the damage is greater than the player's combat level. This lasts 15 minutes. After the week 9 vote, the store price was reduced to 57 Renown.
