Arcana Unleashed expands the game of Dungeons and Dragons in a variety of new ways, adding new spells, subclass options, and even magical items for players to use in their games. However, one of the most underrated parts of the magic themed book is the fresh enemies it introduces, through never-before-seen stat blocks. Some infamous D&D villains finally have numbers behind them, while new foes introduce unpredictable dangers for parties of various levels of play.
One of the reasons why the stat blocks in Arcana Unleashed are so impressive is that they consist less of “monsters,” and more of actual boss or BBEG characters. As a result, there are still some incredibly dangerous villains in D&D who could be utilized through what this expansion provides. Although it may not be the highlight of the book, the magical nature of the enemies featured gives Dungeon Masters a wider arsenal of tools to challenge their players.
The Evoker Archmage is one of several spell casting enemies introduced in Arcana Unleashed, pairing with a longer list of magical foes from the 2024 version of the D&D Monster Manual. Unlike those enemies, though, this mage is a true master of magic, using destructive Evocation spells to decimate players. Although a 16 Armor Class and 214 Hit Points isn’t the biggest threat in Arcana Unleashed, the Evoker Archmage is still a Challenge Rating (CR) 15 enemy, meaning that a group of four Level 15 players are evenly matched against it.
What makes the Evoker Archmage so strong is its innate Trait — Evocation Sculptor. This ability allows the enemy to modify their Area of Effect (AoE) spells, making sure not to target their allies in big blasts of magic. For example, should this enemy cast the infamous spell Fireball, they can choose itself and up to five creatures it can see, sculpting the Fireball’s energy to only target select people. Chosen creatures automatically succeed on saving throws from the Fireball, and take no damage from AoE spells that would normally deal half damage on successful saving throws too.
This magical “monster” also attacks a lot with magic, while having their own resistances against spells cast against it. With a strong Multiattack, the Evoker Archmage can fire up to four Arcane Bursts, dealing ranged Force damage over quite a big range. Although they must recharge spells like Fireball, Ice Storm, and Lightning Bolt, they get to cast two of these spells in succession from one another, devastating D&D characters’ HP. At will, the Archmage can also cast Shatter, Mage Armor, and other useful magic that can be strong outside of combat.
To top it all off, the Evoker Archmage also has Protective Magic as a Reaction, casting Counterspell or Shield to prevent other magic or physical attacks from affecting it easily. This defensive ability is limited, but it goes to show just how flexible this enemy is to many strategies a party of D&D characters might employ. The Evoker Archmage is an easy choice for a final boss, or an incredibly powerful foe for higher level groups to fight.
For players who want to face an enemy designed for lower levels of play, the Spellguard is a perfect opponent. This type of Humanoid foe is rated a CR 5, and acts more like a rival Paladin or Fighter rather than a huge Aberration, Monstrosity, or Undead monster. Yet, this type of enemy is meant to challenge players who rely heavily on magic, countering them with raw physical might rather than an array of offensive spells like the Evoker Archmage.
This is seen the most through the Spellguard’s Superior Magic Resistance, a trait that gives it advantage on saving throws against any spells or magical effects. Spell attack rolls also have disadvantage against the Spellguard, making it much tougher to hit. This enemy already has full Plate Armor for a 20 AC, meaning that landing a blow may be the biggest obstacle to attacking the Spellguard at all. This enemy uses a Force Flail or Javelin to attack, giving it both melee and ranged options to target party members at almost any distance.
Putting the Spellguard with minions or allies makes fighting it even tougher, as it gains the Defensive Divination ability as a Reaction. Whenever an ally within 5ft of the Spellguard gets hit with an attack roll, the Spellguard can spend their Reaction to roll a 1d20, choosing to replace the attack roll if they want. This can cause the attack to miss if the Spellguard rolls low, but the ability also can be applied to saving throws. This makes a high roll using the ability also strong, giving the Spellguard ways of keeping the odds stacked against your party.
Venger is another Archmage in Arcana Unleashed, actually acting as a quest giver for one of the expansion’s new beginner-focused D&D adventures. Yet, this doesn’t mean Venger is a friendly sort, as the Fiend is designed to be a threat at all levels of the game. Possessing a high AC and HP pool, Venger has several damage resistances, with traits that give him the ability to regenerate in one of his lairs even if you do manage to kill him. Should you do take him on, Venger’s magic is not to be underestimated.
One of Venger’s strongest traits only works when he is mounted on a steed of some kind, usually a Nightmare horse made of fire and shadow. While mounted, Venger has advantage on Dexterity saving throws, and can force attacks to target his mount instead. This hints at Venger’s cruelty, which is reflected even more through his standard attacks. Venger can attack using his Crimson Claw or Crimson Blast attacks, with the former dealing additional Fire damage to melee enemies. For a mage, Venger is just as deadly up close as he is slinging spells from a distance.
Some of Venger’s biggest strengths come from his unique Legendary Actions as well, that he gets to use in between player turns during combat. Some of the strongest Legendary Actions Venger has are listed below:
Venger also has access to incredibly strong magic, such as Telekensis as a Bonus Action he can do twice per day. Venger always has Control Weather, Imprisonment, Dimension Door, Alter Self, and other strong spells prepared, including the ever frightening Create Undead. With the ability of Protective Magic just like the Evoker Archmage too, Venger is a truly balanced stat block that makes him a frightening foe, and that’s even without mentioning that he has a 30ft Fly speed.
Although the last expansion, Ravenloft: The Horrors Within, introduced many new eldritch foes for players to face, Arcana Unleashed has at least one more. The Taisus is a Huge-sized Aberration enemy with a CR 19, making it one of the deadliest monsters D&D has created yet. With a 40ft movement speed and 60ft Fly speed, this creature is a highly mobile mass of Psionic energy tied closely to the game’s Mind Flayers and Elder Brains. As a result, the Taisus has immunities to nearly every condition, from Charmed and Frightened to even Paralyzed or Restrained.
The Taisus is essentially immortal, regenerating from dust using an arcane resilience that players have to use a Wish spell to revert. However, should your party still desire to fight the Taisus, it fights back using Brain Drain attacks that consume spell slots and deal Psychic damage to characters. The Taisus feeds on magic, making it a deadly predator of spell casting characters in D&D at times. The creature itself has access to strong magic too, including Fireball, Jallarzi’s Storm of Radiance, Befuddlement, and even Disintegrate.
Like Venger and the Evoker Archmage, any Taisus you encounter also has the Protective Magic reaction to defend itself at any time. With Legendary Actions letting it do an additional Brain Drain attack or teleport, this parasitic monster is a horrifying enemy under any circumstance. Although not as well-rounded as other stat blocks on this list, the huge threat this monster poses to magically inclined characters makes it worth using against a party that relies too heavily on their spells.
There are few names in D&D as feared as Szass Tam, the Undead Lich ruler of the Red Wizards of Thay, a figure who has haunted the game’s narrative ever since its 5th Edition was released. This enemy is a final boss for Arcana Unleashed‘s new Level 11-20 adventure of the same name, with Szass Tam having a terrifying CR 23 rating, a score usually reserved for Tiamat, Vecna, and other major villains. Every part of Szass Tam’s stat block reflects his status, with multiple condition immunities and damage resistances that make him a challenge right away.
Szass Tam has a 20 AC and 397 HP, but revives in his Spirit Jar if destroyed within 1d10 days, solidifying his position as an immortal Lich. If players have broken his spirit jar, Szass Tam is vulnerable, but his magic makes it incredibly difficult to strike at him directly. Szass Tam will use everything to his advantage, including Finger of Death, Fireball, Lightning Bolt, and Power Word Kill to damage his enemies. At the same time, spells like Animate Dead, Project Image, Plane Shift, and Dimension Door can Szass Tam out of trouble if threatened.
Much like other magical foes, Szass Tam has access to the Protective Magic Reaction, but his main Paralyzing Touch and Soul-Draining Ray actions are by far his deadliest tools next to his magic. Szass Tam has a chance to Paralyze targets with a touch, causing them to take automatic Critical Hits with melee attacks if the condition lingers. Meanwhile, the Soul-Draining Ray ranged attacks can give a target disadvantage on their attack rolls and saving throws, hindering them until the end of their next turn. Similar to Venger, Szass Tam also has an impressive array of Legendary Actions, including:
Combining all these abilities together makes Szass Tam one of the strongest enemies in D&D as a whole, rivaling some of the biggest and baddest evil guys Wizards of the Coast have ever designed. As such, his presence can be instantly intimidating even outside of a combat setting, making him a legendary figure to use within your games. While it might be extremely difficult to fight Szass Tam in Dungeons and Dragons, simply having such a high-level enemy in Arcana Unleashed expands the list of challenges your party could face at the end of memorable journeys.
