The player must defeat a Darkwraith located at the bottom of a tower in the High Wall of Lothric after receiving the Lift Chamber Key provided by Ringfinger Leonhard once they have obtained a Pale Tongue.
From the Tower on the Wall bonfire, make way to the bottom of the tower and unlock the barred door with the key given by Leonhard. Ride the lift down and fight the Darkwraith there. The item will be automatically added to the player's inventory once he dies.
Using this infinite consumable will allow a player to invade another player's world as a dark spirit. A Host of Embers can only be invaded in this manner if the boss for the area is still alive. Unlike in the first Dark Souls, usage of this item is not restricted to any specific covenant, and victory requirements will vary depending on the covenant that the player has pledged themselves to.
Invasion ranges can also vary depending on covenant status. In all cases, invasion range is based on the player's Soul Level.
|Invasion type||Lower Limit||Upper Limit|
|Red Spirit (below level 351)||90% of player's Soul Level||110% of player's Soul Level + 20|
|Mound-makers (below level 351)||90% of player's Soul Level||115% of player's Soul Level + 20|
|Any (level 351 and higher)||Soul Level 351||None|
