Makhleb

''Makhleb the Destroyer is a fearsome deity of bloodshed and mortification of the flesh. Followers are expected to cleanse others by inflicting suffering and death on them in Makhleb's name, and can gain further favour by ravaging the freshly dead. Dedicated followers may also access the raw energies and hell-spawned servants of chaos, so that they may better break the impure world and its false laws for this evil God's glory.''

Makhleb the Destroyer is a God in Dungeon Crawl

Followers of Makhleb gain the ability to gain health from kills and summoning demons should their piety rise high enough. This means that the god is suited for a Deep Dwarf as the healing on kills offsets their inability to gain health naturally.

Worshipping Makhleb will require training in Invocations, as it is the primary stat for all granted abilities; failure to cast summoning spells could potentially result in summoning hostile demons, making it very important to have at least 10-15 in invocations before relying heavily on summons.

In-Game Description
''Makhleb offers followers various means to inflict immense damage, and to call in help from powerful demons, although these powers come with a price in blood. However, Makhleb will grant followers renewed health in return for killing beings of all kinds.''
