The aegis blood essence is one of the blood essences players can craft after the quest River of Blood. Using Haemalchemy, players can combine 100 congealed blood with a 4-dose guthix balance potion; doing so requires at least 200 vyre corpses to be cremated in the Columbarium. When received as a one-time gift from Vanescula Drakan after the quest or created manually, it will have 1,000 charges. Additional charges can be added by using more congealed blood on the essence, giving 10 charges each, to a maximum of 5,000 charges. If charges are completely exhausted, the essence's effects no longer function, but it can still be worn.
When worn, it has a passive effect that has a chance of reducing damage by 5%, by a minimum of 5 and a maximum of 250. Hits below 5 will not trigger the effect. When activated, the next hit within 20 seconds is reduced by 50%, by a minimum of 50 and a maximum of 2500. Hits below 50 will not trigger the effect.
The active effect can be used once per minute. This cooldown is shared with other blood essences, except the tireless essence. Each activation of the passive effect consumes 1 charge and each use of the active effect consumes 50 charges.
Having a blood essence equipped and attempting to enter the Mausoleum notifies the player "You have a blood essence equipped which makes the ravenous ghouls aggressive. Are you sure you wish to proceed?"
According to the book Haemalchemy (Vol. 2), this blood essence is described as:
Platelet activity is increased ten-fold, and white blood cells will also take on a temporary mineral-like state to make the blood viscous and absorb kinetic energy.
