Coatyl (Unnamed Dungeon Crawler)

Coatyl is a playable character in Unnamed Dungeon Crawler who originally appeared in Valhalla: The Story of the First Sage. He only starts with 1 Red Heart and 1 Mana Heart, but this is balanced by his Banished Tome, Stitched Hand, and Pocket Altar.
== Gameplay ==
Coatyl actively encourages a cautious, decisive playstyle, as he cannot obtain more Red Hearts. The player must decide which hearts to sacrifice for stats/Mana while making sure not to take further damage from sources to maximize Coatyl's Mana. However, if done right, it can be very rewarding, as Coatyl deals more damage depending on the amount of Mana or Banished Hearts he's holding. As Coatyl, sacrificing a Banished Heart temporarily reduces the Mana cost of spells, Silences all nearby enemies for a few seconds, and restores 1 point of Energy. It's also worth noting that Coatyl has a 20% chance of finding Mana Hearts and a 40% chance of finding Banished Hearts. In multiplayer, these odds are modified for balancing reasons.
His passive item, the Stitched Hand, causes Coatyl to Silence enemies after getting hit, and his Banished Tome always inflicts Darkness.
== Strategy ==
First and foremost, Armored Hearts are pretty much useless to Coatyl aside from the extra hit points they provide. He also can't wield guns or melee weapons, so if he runs out of Mana, it's best to use throwing weapons as an alternative. He can still keep said weapons in his inventory, making the Vintage Milk quest doable.
== Synergies ==
Coatyl + Flicker: Coatyl will phase in and out after sacrificing a heart, making him invincible for a few frames.
Coatyl + Death Whistle: Refills 2 Mana per use.
Coatyl + Gothic Dirk: Coatyl has a 10% chance of receiving a Banished Heart when slaying an enemy.
Coatyl + The Accumulator: Drains health faster, consuming Mana Hearts before any other heart type.
== Trivia ==
* A Coatyl, Coatl, or Couatl is a monster from D&D Beyond that takes on the form of a long, winged serpent.
* The last sentence of Coatyl's description is a reference to ULTRAKILL. This statement still perfectly reflects Coatyl's core gameplay mechanic as well, since he uses Mana and Banished Hearts to increase his Mana.
* Coatyl's role as a dark mage is due to his role in other installments of the series, where he owns a black magic store by the name of Dark Omen.
