Arch-vile

Arch-Viles are frail-looking, yellowish-skinned humanoid figures with a grotesque appearance, including stigmata. They also have no flesh around their abdomens, revealing some of their ribcage. Arch-Viles first appeared in Doom II.

Arch-Viles take a deceptively high amount of damage (700 HP), and their attack consists of a unique ability to immolate their enemies in flames by raising their arms up, summoning fire upon the targeted foe, regardless of range (though they will not use their attack from more than 1024 map units away unless hurt). They then hunch over and clasp their hands together, causing the fire to erupt, usually send the enemy flying into the air, while causing up to 90 points in damage. This attack will always hit the enemy as long as there is a line of sight between the Arch-Vile and the target, and can be avoided by hiding behind walls.

Arch-Viles are the fastest non-flying monsters in the game, and meeting two of them at once spells doom for most players.

The Arch-Vile has the power to resurrect other, lower-level monsters. They can revive all monsters except Cyberdemons, Spider Masterminds and other Arch-Viles (although they can resurrect Lost Souls, this is an extremely rare occurrence). This power makes them top priority to kill in battle, to stop them from reviving monsters and forcing the player to waste precious ammo. However, the player does get credit for killing resurrected monsters, so in levels containing an Arch-Vile the KILLS percentage displayed at the end may exceed 100%.
