Notes for the game master

Focus on using reach to prevent players from closing in.
Use Boiling Blood Spray when multiple targets are lined up.
The Sanguine Chitin trait makes melee combat dangerous for low-HP attackers.

Tactics

  1. Opening

    Krevat starts the encounter clinging to the ceiling or a pillar, using his reach to strike down at the party as they descend the staircase. He opens with Boiling Blood Spray to blind as many targets as possible.

  2. Mid-fight

    He moves to the center of the staircase, using his Sentinel feat to stop players from bypassing him. He targets healers and spellcasters with his long-reach glaive.

  3. End of the fight

    When reduced to below 40 HP, Krevat enters a frenzy, using his Legendary Actions exclusively for Blood Pulse to keep the party grouped for his spray.

  4. Retreat

    Krevat is fanatically loyal and cannot be intimidated or persuaded to leave his post. He fights until he is destroyed.

How it fights

Utilize the 10ft reach of the glaive to trigger opportunity attacks when players try to move around him.
Keep at least one target blinded at all times if possible.
Use Skitter to reposition if surrounded, avoiding being pinned in a corner.

Who it attacks first

Spellcasters with cold-based magic
Healers
The creature currently standing closest to the staircase entrance

Works well with

Works well with Drow Mages who can cast Web to restrain targets for Krevat's spray.
Synergizes with Blood Spiders that can provide distraction and additional poison damage.

How to beat it

Cold damage (bypasses resistances and deals extra thematic damage)
Ranged kiting from beyond 10 feet
Spells that restrain or grapple from a distance

Ways to avoid a fight

If the party bears the Signet of House Valen'dros, Krevat may allow them passage, though he will watch them with visible aggression.
Disguise Self or Illusion magic could potentially trick him, but his Web Sense makes this difficult if the floor is covered in silk.

Ecology

Krevat is a towering, horrific fusion of a Drow noble and a giant spider. His lower spider body is made of translucent, ruby-red chitin that glows with an internal light, revealing pulsing sacs of boiling blood. His upper elven torso is scarred with glowing runes and encased in jagged black plate armor. He wields a massive glaive that continuously weeps a thick, corrosive red sap.

Behavior

Krevat is fanatically loyal and stands motionless at the Sinking Staircase until intruders arrive. He does not speak, only emitting a low, wet hissing sound as blood pumps through his body. He fights with zero regard for his own safety, using his own injuries to spray acid and heat on his enemies.

How it lives

Krevat is a unique specimen created by House Valen'dros. He does not eat in a traditional sense, instead drawing sustenance from the magical blood rituals performed by the sect priests.

Lair

The Sinking Staircase, a spiraling stone descent covered in calcified webs and stained with centuries of ritual blood.

Habitat
Underdark, Magical Vaults, The Undermyr

Signs that it is near

Thick, ruby-colored webs that feel hot to the touch
Splotches of dried, acidic red resin on the floor

Lore

Once a high-ranking captain of the guard, Krevat volunteered for the Sanguine Ascension ritual to redeem his family's name. The ritual involved the forced infusion of Blood Spider eggs into his marrow, transforming him into a living engine of defense. He now stands as the final barrier before the sect's inner sanctum.

What drives it

Krevat exists only to prevent unauthorized entry into the lower vaults of House Valen'dros. His loyalty is magically bound to the House Matron.

After the fight

Upon Krevat's death, his blood sacs rupture, coating the Sinking Staircase in a permanent, slippery red film that smells of iron and sulfur. The warding spells on the lower vault doors flicker and weaken, signaling the path is open.
