Necromancy is a secondary skill from Heroes of Might and Magic II. It raises some of the units killed in battle as Skeletons.
- Basic Necromancy raises 10% of the units killed.
- Advanced Necromancy raises 20% of the units killed.
- Expert Necromancy raises 30% of the units killed.
The number of the raised skeletons is rounded down but at least 1 skeleton is always raised if any unit died in battle. Unlike the following installments, Necromancy in Heroes II raises the undead and elementals as well.
Necromancers start out with basic Necromancy. Only Necromancers and Warlocks can learn Necromancy.
