Circle of Life

Circle of Life is a achievement/trophy in Dishonored 2.
==How to Acquire==
Corvo Attano (or Emily Kaldwin in New Game +) must cast the supernatural ability Possession and chain between a human host, a wolfhound or gravehound, a rat, a fish and a bloodfly in any order before the effect ends. Possession and all of its upgrades must be unlocked to be able to chain between hosts, possess a human and last long enough to complete the chain.
As wolfhounds and gravehounds are limited to only certain areas in the game, and fish cannot leave the water, their presence in an environment should be the main consideration in approaching this achievement.
The easiest place to chain between a member of each species is during the mission The Royal Conservatory. First enter the Royal Conservatory through the basement and possess the gravehound patrolling on the other side. Go outside and down the stairs on the right then switch host with a rat. Switch host with one of the bloodflies nearby and fly through the large pipes to the fountain outside the building. Switch host with a guard patrolling nearby then switch with one of the fish in the fountain.
As with many challenges in the game, there are any number of ways to approach the achievement, but the Bloodfly Swarm upgrade of the Shadow Kill power gives a much greater degree of freedom of approach. For example, one can alternatively unlock the achievement during the mission The Grand Palace using this ability, right at the palace's entrance gates. 
As another alternative, The Addermire Institute provides a means of completing the challenge, by bringing a human to the front of the Institute (near the pool with the fish, and the wooden walkway with the rats). Then, lure the white wolfhounds from their containment near the barracks to the pool, kill one of them to turn it into bloodflies, and chain between the creatures as needed. Finding a slightly higher vantage point, like the crates to the right of the pool, helps prevent wolfhounds from attacking while performing the initial possession.
