Guardian Angel (Tier 3) detail

Guardian Angel (Tier 3) can be obtained from the Zamorakian quartermaster or the Saradominist quartermaster during the Battle of Lumbridge for 90 Renown. A player can "Drink" this item and then the next four attacks they receive during battle will be a single point of damage, if the damage is greater than your combat level. This lasts 20 minutes. After the week 9 vote, the store price was reduced to 85 Renown.
