Mana will be drained faster when the player is immobilized by a Shadow Charger. They can also emit a Darkness aura which will raise the defense of all monsters within range.
Laguz - This Water Spirit attacks by releasing 3 bubbles in front of them and popping them, which will damage and inflict Frostbite.

Ancient Cockatrigle - A beefed up version of the Cockatrigle. They have slighly more chains on them and a orange/black coloring. They have an extra rushing attack as well.
Fallen Chloe - Chloe returns, corrupted by the forces of darkness. She has lost her bow, so now her moves are pretty much like Wind Sneaker's.
Many find Chloe significantly more difficult to defeat than Victor due to her extremely high damage output, defense, speed, and ability to combo with special actives.
-Advanced Kick Combo: Starts with 2 normal kicks followed by 3 powerful kicks: A rear horse kick, knee kick and a long range knee kick. Similar to Wind Sneaker combo ZZ→ZZZ.
-Slash: Chloe draws her knife and slashes you TWICE with it. Induces KD and Bleed (see Status Effects)
-Tumble: Jumps into the air and turns upside down as it's turning its head into a giant spike before making a sharp fall, tends to do this to attack players through platforms. Induces KD.
-Air Kick Combo 1 & a half: Chloe performs the Triple Air Kick maneuver. However, she only stops at the second kick and starts combo-ing you later.Similar to Combat Ranger combo →→↑ZZZ canceled on second Z.
-Nature Force: Dark Ver.: Chloe imbues her attacks with the power of darkness. Similar to Wind Sneaker's Nature's Force active skill.
-Spinning Kick: Dark Ver.: Chloe spins horizontally, drilling into opponents with her feet. Similar to Combat Ranger's Spinning Kick special active skill. This does substantial damage.
-Slide Double Kick: Dark Ver.: Chloe slide kicks behind the you followed by a kick and another kick into the air. Similar to Wind Sneaker's Slide Double Kick special active skill. This does enormous damage.
-Has a stoic threshold of 20 hits.
-Like most Dark Elves she has 10% evasion allowing her to avoid attacks.
This works differently than a player's evasion and makes her immune to that player's attacks for several seconds each time it activates.
Black Flower - Black Flowers are plants located on the bottom of various platforms. They will attack by emitting poison gas downwards to poison any players directly under them. After killing one, they will emit a toxic cloud to poison any players that are close to it.
Giant Gear - Giant gears will run through the two large water canals, these large gears will run into and launch anything, monsters included into the air.
Portal - This portal doesn't attack you, it transports you to farther into the waterway canal and onto the central lift.
Victor - One of the more aggressive bosses in Elrios. Possesses superhuman strength and loves violence.
-Dynamic Entry!: Only does it at the start of the match. Victor leaps down from his post and smashes the center of the stage, roaring once he hits the ground. He cannot be damaged until he has finished roaring.
Both the impact and roar can deal damage.
On each side of the stage there are two starting positions for players, the one on the left closest to the center is in range of the impact. Simply move a little to the left to avoid getting hit.
-Victor Combo: Poses then strikes in a certain direction three times. Unlike when fighting him as a boss this attack has no super armor frames.
-Victor Swing: Poses then swings his fists into the air to throw you upwards while in super armor.
-Victor Charge: Occurs only if you are at a certain distance away from him. It's similar to Burning Rush, except debris will fall from the ceiling on impact with a wall.
-Victor Assault: Victor roars, beats his chest rapidly, and then launches himself at the nearest target. He lands on them and violently attacks them repeatedly for enormous damage.
If he fails to land on a valid target he will not continue with his combo.
-Body Slam: Body Slam that will inflict Flattening for a period of time. Very fast and powerful but requires that he jumps before performing it.
-It's Showtime!: Victor leaps into the air and tries to crush you with his weight. He roars after he lands. However, this move can be avoided easily as he only lands on your initial spot, so walk away from it.
-Has a stoic threshold of 30 hits.
At the top of the elevator, there are four prongs. However, as the elevator descends, the rear prong is missing, and at the bottom, the front prong is missing.
On Very Hard mode only. In the room before the boss, there is a box somewhere in the upper left corner. Skills that can reach high places such as Elemental Master's Blizzard Shower or Magic Missile can break it and items will fall down.
There is a bug where you are unable to move even after Victor has jumped down. This can easily be resolved by using a consumable item.
Elemental Master's Frostbite Sphere causes Victor to lose his collision box when he is Frostbitten, be wary.
