Necropolis - Special buildings | Necropolis - Buildings Heroes VII Guide

Sacrificing living creatures is profitable only in rare cases.

When developing the Necropolis cities, you can construct one special building - Altar of Sacrifice. Building it will allow you to use additional option available in the lower city menu. By sacrificing part of the gold, you can transform selected living creatures into Skeletons or Skeleton Hoplites, thus strengthening your army. By sacrificing a basic creature you will receive a regular Skeleton while after sacrificing an upgraded creature you will receive a Hoplite. It is wise to think if it is profitable for you. You should sacrifice units only under two conditions. First, you should only sacrifice weak and very weak creatures. Second condition is the lack of free slots in the army for additional troops. Remember that the troops you created will almost always be much weaker than the ones you sacrificed.
