Monsterwright

“Where others see nightmares, I see design potential.”

— Serik the Graftwright, First Disciple of the Monsterfather

 

As a Monsterwright, you delve into the forbidden intersections of science, alchemy, and anatomy. Drawing on the blueprints of monsters and legends, you create living weapons of your own design—fused from flesh, bone, and story. Your Monstrous Companion acts as both a battlefield ally and a canvas for your disturbing artistry, while your ability to graft traits onto others makes you an architect of evolution. Whether you're a mutagenic savant or an unsettling genius, your work speaks through claws, eyes, and teeth.

Tool Proficiency

3rd-level Battle Smith feature

You gain proficiency with leatherworker's tools and alchemist's supplies. If you already have this proficiency, you gain proficiency with one other type of artisan’s tools of your choice.

Monsterwright Spells

3rd-level Battle Smith feature

You always have certain spells prepared after you reach particular levels in this class, as shown in the Battle Smith Spells table. These spells count as artificer spells for you, but they don’t count against the number of artificer spells you prepare.

Battle Smith Spells

Artificer Level	Spell
3rd	command, shield
5th	alter self, mirror image
9th	bestow curse, vampiric touch,
13th	greater invisibility, polymorph
17th	contagion, wall of force

Trait Grafts

3rd Level Monsterwright Feature.

You can graft one monstrous trait from the Monstrous Traits Table onto your Monstrous Companion during a long rest.

• At 3rd level: 1 trait
• At 9th level: 2 traits
• At 15th level: 3 traits
• At 9th level, you may also change grafts during a short rest

You may also graft one trait onto a willing non-companion creature during a long rest. Non-companions may only have one graft at a time. The grafting process is painful:

• The recipient takes 1d6 + 4 slashing damage and 1d6 + 4 psychic damage and the psychic damage cannot be healed until the next long rest.
• They must make a DC 15 Constitution saving throw; on a success, they take half damage. All damage may be healed as normal

You may only perform one graft operation per long rest (add, remove, or change). This improves to once per short rest at 9th level.

 

Monstrous Traits Table

Monstrous Companion

3rd-level Monsterwright feature

Your craft has borne you a monstrous companion. It’s friendly to you and your companions, and it obeys your commands. See its game statistics in the Monstrous Companion stat block, which uses your proficiency bonus (PB) in several places. You determine the creature’s appearance. Its appearance has no affect on game mechanics or statistics.

In combat, the companion shares your initiative count, but it takes its turn immediately after yours. It can move, attack, and use its reaction on its own. If you are incapacitated, the companion can take any action to defend you.

If it has died within the last hour, you can use your leatherworker's tools and alchemist supplies as an action to revive it, provided you are within 5 feet of it and you expend a spell slot of 1st level or higher. The monstrous companion returns to life after 1 minute with all its hit points restored.

At the end of a long rest, you can reconfigure your monstrous companion if you have leatherworker's tools and alchemist's supplies with you. If you die, the companion will follow your allies around but won't obey any commands it doesn't want to.

Mythic Surge

5th-level Monsterwright feature

Once per turn, when your Monstrous Companion or a grafted creature hits with a weapon attack, you may force the target to make a Constitution saving throw (DC = 8 + your Intelligence modifier + your proficiency bonus).

• On a failed save, choose one condition: Poisoned, Frightened, or Paralyzed
• The condition lasts until the end of your next turn

You may use this feature a number of times per long rest equal to your Intelligence modifier (minimum 1).

Monstrous Refinement

9th-level Monsterwright feature

• Your Monstrous Companion can now have two traits
• You may now add, remove, or change grafts during a short rest
• Once per day, you may create a Monstrous Clone:
• Lasts 1 hour
• Uses the Homunculus Servant stat block
• Has 1 trait from the Monstrous Traits Table
• Your Monstrous Companion gains an additional attack (2 attacks per action)

Monstrous Overload

15th-level Battle Smith feature

You have reached the apex of biological artifice. Your Monstrous Companion now makes three attacks when it takes the Attack action.

Once per long rest, you may use a bonus action to activate one of the following Overload Modes, which last 1 minute:

 

Overgrowth

Your companion grows into a towering abomination.

• Size increases to Large
• At the end of each of its turns, it gains temporary hit points equal to your artificer level
• While transformed, it makes only two attacks per turn (not three)

 

Spawnstorm

Your companion splits into three Lesser Spawn:

• Each spawn has the same AC and HP as the companion
• Each makes 1 attack per action and has 1 trait
• They act on your initiative
• After 1 minute (or if all are destroyed), the original companion reforms

 

Trait Cascade

You trigger a wave of mutation across your allies.

• All creatures with a graft gain:
• +1 additional trait
• +1d6 psychic damage on melee attacks
• Immunity to the frightened condition
