Spirit Beasts

The four Spirit Beasts are very rare unique beasts that, upon using their Blood Altar recipe, will open six portals to their realm, a small linear map leading up to a boss fight, akin to vaal side areas.

Defeating one of them in its realm will reward you with one item of its respective set, and the component to craft its aspect, as a suffix, on a piece of gear.

Note that, to craft the aspect, you will need to defeat that spirit beast at the blood altar, which is a smaller area with only one try.
