Summoner

The summoner is a new form of the arch-vile in Doom (2016). It is a tall, levitating, blue- and purple-colored demon with a bony crown-like ring around the top of its head. When attacking, it takes on a pose reminiscent of the original monster, with its arms held up above its head in an arc, channeling energy through its hands. It has two insect-like wing covers attached to its back, perhaps an echo of the moth-like Mother Demon who also held a close connection to the arch-viles.

Tactical analysis
Unlike the arch-vile from Doom 3, the summoner can continue to summon demons rapidly until it is defeated. It will teleport around the area it appears in, using projectile attacks that deal medium to high amounts of damage to whatever it hits. It can summon every kind of standard enemy that has appeared up to that point in the game. Unless the player prefers the company of several Hell knights, it should be killed without hesitation. If there is a berserk power-up available or if enough chainsaw fuel is on hand, these are not at all overkill for use on it.

Pre-release
The summoner was known as the arch-vile in pre-release versions of the game, with all of its codex entries referring to it as such. This was changed very close to the game's release.
