An avatar can own more Blood, Cider or Lumen wealth than the amount that fits in their bodies. This overflow is held in containers of various types, and is totalled for purposes of Weatlh Rankings.
Storage Containers for Blood, Lumens, Ether, Ichor, and Cider
Each player can hold up to 5L of Vital Blood, 50 Lumens, 50A of Ether, or 5T of Ichor within their body. If more is desired, excess metrics can be stored in containers. These containers can also be used to buy, trade, and sell metrics. Blood can be stored in Blood Tanks or Blood Casks, Lumens can be stored in Iron Prisms or Bone Prisms, Ether can be stored in Ether Vessels, and Ichor can be stored in Ichor Urns.
Metric purchases made from places other than the official Bloodlines stores on Liquid Designs property are not guaranteed. You may be able to obtain a better price elsewhere, but there is risk involved, and in making purchases from unofficial sources, you accept this risk.
Cider containers can be drank from to restore humanity, but can only be refilled by Cider Jugs. Humanity cannot be turned back into Cider.
It is always safe to purchase containers from Bloodlines; there is some risk involved in purchasing containers from other avatars, and from the Marketplace.
