Deva

The devas are a group of angelic beings added in SLASH'EM. They are all characterized by strong physical attacks, high speed, and clerical spellcasting, similar to aligned priests. They are most often encountered as minions, either given to lawful characters through prayer or sacrifice, or created when attempting to convert a lawful altar. As minions, they are quite powerful, and can be a useful source of shields of reflection or even artifact weapons, which they have a chance of starting with.

Movanic deva
The movanic deva is the weakest of the devas. It is still a formidable opponent, particularly if one lacks fire resistance, as its attacks will then burn you. It is able to cast clerical spells, including possibly curse items.

Monadic deva
Monadic devas are slightly stronger than movanic devas, and are distinctive in that their physical attacks do only normal damage. Still, they are quite formidable opponents, similar in level to an Angel but much faster. They are also able to cast powerful clerical spells.

Astral deva
The toughest of the devas, astral devas are almost equivalent to an Archon in difficulty. They do similar amounts of physical damage, and while the astral deva cannot stun and blind with its gaze, it can stun with its physical attacks. The astral deva is also slightly faster than the Archon, with a speed of 18 over the Archon's 16. They are almost the same base level (18 for the astral deva versus 19 for the Archon), and are both spellcasters. Luckily, the astral deva is unable to summon nasties, as it can only cast clerical spells, which summon nasties luckily is not. It is also not guaranteed a shield of reflection, although it does resist death rays, but not other types of rays. Its high MR means that little but elemental damage is likely to be effective, though.
