Collector Beetle

“Roughly the size of a mastiff, these creatures resemble large black beetles. Without a rigid shell of their own, they wrap themselves in artificial armor. When possible, these creatures seem to prefer creating their shells from the remains of other creatures. We don’t know what prompts this behavior, but the sight of a Collector Beetle buried under a mass of bleached bones is impressive.” –Traveling researcher

Communal Scavengers: Collector beetles often travel together, seeking new pieces to add to their shells and more of the fungus and moss that makes up their diet. While not typically aggressive, they have been known to swarm when threatened.

Macabre camouflage. Collector beetles have little in the way of defenses. Without claws, fangs, or other natural weapons, larger beasts often see these creatures as easy prey. To protect themselves and blend in, these giant insects create shells of hard refuse that they find while scavenging, gluing bits of metal, wood, and especially bone to their backs with their sticky saliva.

Shy Collectors. Typically, collector beetles prefer to use light substances like wood and bone to make their armor, but some occasionally find more valuable components. Gold coins, pieces of jewelry, and even weapons have been known to find their way onto a collector beetle’s back.

Scavenged Defense. While its shell is intact, a collector beetle can attempt to avoid damage by pulling into its shell. When a collector beetle is struck by a melee weapon, it may use its reaction to roll a d6. On a 3-4, the attack damages the shell instead of the beetle. On a 5-6, the attack damages the shell, and rubble knocked loose from the shell deals 1d4 piercing damage to any creature within 5 feet of the collector beetle. Once the shell has received 10 points of damage, it can no longer use this ability until it completes a long rest.


Slam. Melee Weapon Attack +4 to hit, reach 5 ft., one target. Hit: 9 (2d6 + 2) bludgeoning damage.

Sticky Spray.  Ranged Weapon Attack +4 to hit, range 20/40 ft., one Medium or smaller creature. The creature is coated in a thick, foul-smelling fluid that rapidly begins to harden. The creature is restrained (escape DC 10). The effect ends if the restrained creature takes any damage.

Guardian Soul

A woman’s pale, translucent form clad in plate armor stands behind a young boy. It doesn’t speak or lift its ephemeral blade, but its presence radiates a warning. Don’t come any closer.

Protectors in life. Guardian souls are born from the urge to defend. Occasionally, when knights, loyal bodyguards, and even parents die while protecting someone, they rise again as spirits with honed warrior instincts and an overwhelming desire to protect.

Protectors in Death. Relentless, guardian souls remain bound to whatever charge they served in life, whether their charge wants them or not. Silent and alien, a guardian soul can be a powerful shield or a potent reminder of a lost friend.

Guardian Soul

Medium undead, any lawful alignment

Armor Class 17 (natural)

Hit Points 135 (18d8 + 54)

Speed 30 ft., fly 30 ft.

Challenge 10 (5,900 XP)                 Proficiency Bonus +4

Bound In service. The guardian soul cannot go farther than 30 feet from its master. If its master dies, the Guardian Soul is also destroyed.

Incorporeal movement. The guardian soul can move through other creatures and objects as if they were difficult terrain. It takes 5 (1d10) points of force damage if it ends its turn inside an object.

Spectral Armaments. The guardian soul’s attacks count as magical for the purpose of damage resistances.


Multiattack. The guardian soul makes two longsword attacks. It can use its Strength Drain in place of one of these attacks.

Longsword. Melee Weapon Attack + 8 to hit, reach 5 ft., one target. Hit: 18 (4d6 + 4) slashing damage.

Strength Drain. Melee Weapon Attack + 8 to hit, reach 10 ft., one target. Hit: 13 (2d8 + 4) necrotic damage. The target must succeed on a DC 15 Constitution saving throw or have its Strength score reduced by 1d4. This reduction lasts until the target finishes a long rest.

Willing Vessel (Recharge 6). The guardian soul enters their master’s space, possessing them. While possessed, the target gains resistance to all damage and is not incapacitated. The guardian soul cannot be targeted by any attack, spell, or another effect, except ones that turn undead. Whenever the possessed creature takes damage, the guardian soul takes the same amount of damage. During the guardian soul’s turn, they can control the host’s body but use their own statistics when making attack and damage rolls. The possession lasts until the host drops to 0 hit points; the guardian soul ends it as a bonus action or is turned or forced out by a magical effect.


Spectral Shield. When a creature makes an attack against the Guardian Soul’s master, they grant their master a +2 bonus to AC if they are within 10 feet.

The Tower, Titan of Ruin

“We looked upon it and wept in awe—a colossus. In the shape of a human figure made from porcelain or marble, its enormous size tore through the clouds as it walked. It was featureless, without eyes it had no pity, and without ears, it was deaf to the screams left in its wake.” -fragmented account from the library of Watchers.

Hidden Titan. Appearing as a regularly sized humanoid figure with stark white “skin” and no discernible features, the colossus travels secretly. The creature can grow to immense size very quickly, often using its smaller form to enter towns and cities before increasing its size exponentially, destroying the site from within.

Unknown Purpose. It is unclear what draws the ruin or why it does what it does. When the titan does act, it’s thorough, using its great size and physical power to destroy all buildings and infrastructure it can find. When finished, the creature seems to vanish—likely reducing its size and slipping away in the chaos with the attack’s survivors.

Omen of Ruin. Many believe that the titan’s appearance is an omen of inevitable calamity, though this may be simply a case of direct causation.

Crush. Melee Weapon Attack + 17 to hit, reach 15 ft., one target. Hit: 31 (4d10 + 9) bludgeoning damage. If the target is a creature and the tower is currently Huge or larger, the titan can choose to grapple them (Escape DC 19). Until this grapple ends, the target is restrained. The tower can have two creatures grappled at once.

Throw rock (Huge and Gargantuan Only). Ranged Weapon Attack + 17 to hit, range 90/180 ft., one target. Hit: 35 (4d12 + 9) bludgeoning damage. If the tower is currently grappling a creature, it can throw that creature instead of a rock. In addition to the regular attack, the thrown creature must succeed a DC 19 Constitution saving throw or take 18 (4d8) bludgeoning damage on impact, taking half damage on a success. The thrown creature is knocked prone on landing.

On a success, creatures take half as much damage and are not stunned.

Objects and structures automatically take full damage.
