A Blood Host Detachment (the force organization chart in the codex) allows you to field two Bloodthirsters in your army. Also you get more as they can be summoned from the Blood Tithe.
The Blood Tithe is a special rule that allows you to gain Blood Tithe pts every time you kill or lose a unit.
Expending Blood Tithe pts gets you abilities which are on the 8 Blood God cards from the datacards set. The first one which is shown in the mag, is Infernal Contempt- which costs 1 Blood Tithe pt and grants all friendly units with the Blood from the Blood God special rule to gain Adamantium Will until the start of your next turn.
You can spend your points once a turn to summon some daemons or give abilities to your units
8 Points you will get a Bloodthirster for free.
