The Shade is a rare monster that appears only in very special circumstances in a select few dungeons. It appears in only four dungeons: Namtar's Lair, Creeplight Ruins, the Cursed Oasis, and the Tower of Gaan-Telet. This rarity is fortunate, since the Shade is one of the nastiest monsters in the game with its combination of lifesteal, blinking, and physical resistance.
Like all blinking foes, Shades are very difficult to fight early in exploration, since they are likely to teleport into unexplored territory. However, there is the added danger that a shade that teleports into unexplored areas has an opportunity to life steal you for a second time. Due to their high physical resistance and the life they have stolen it will be very difficult to kill them in a single blow, leaving few easy approaches to take down this monster type.
The easiest way to fight Shades is by waiting until the level is mostly explored. This mitigates the difficulty presented by their blink/lifesteal combo, but this is not always an option if you want to fight them early. The WEYTWUT glyph is one of your only reliable approaches to prevent the monster from blinking away. Knockback effects also work, but if you push the wraith into unexplored territory it will lifesteal from you again, so careful positioning is required to take this approach.
In most dungeons, there are ways to avoid Shades. In Gaan-Telet, they will have bloodstains surrounding them, allowing you to reveal them when you're injured to minimize the amount of life loss. In Creeplight Ruins, the cultists will only transform after you slay the sacrificial goat. If you simply wait until the dungeon is mostly explored the Shades won't be a problem at all. However, there is no easy way to avoid Shades in Namtar's Lair or the Cursed Oasis. On the Cursed Oasis, dealing with Shades will be one of your biggest challenges.
There is a mini-boss in the Cursed Oasis level who is a shade. Defeating him is not technically necessary to win that dungeon, but may be unavoidable.
