Homebrew:Mimicry
(OOC: This is an implementation of the Mimicry subclass from Tasha's Crucible of Everything Else volume 2)
Base Class: Wizard
The mimic. A devious hunter, every rogue's nightmare, and the last thing some creatures see before being swallowed whole. The first mimics were created by powerful mages, and they were intelligent creatures, combining tactical prowess with an all-consuming hunger to create terrifying and powerful devourers. While the secrets of how to create those beings have been lost to time, some mages have passed down a similar tradition that allows even novice wizards to create the monstrosities that many dungeon delvers have become familiar with, commanding these monstrosities as subordinates through sheer power of will.
Transmogrify
2nd-level Mimicry feature
As an action, you can spend a spell slot and touch a nonmagical object that isn't being worn or carried to turn it into an experimental mimic of the same size. This mimic uses the arcane mimic stat block. Some details of this stat block vary based on the spell slot used to create the mimic and the size of the mimic, as described in the Transmogrification and Arcane Mimics tables.
The spell slot used determines the mimic's Strength score and the maximum size of item you can transmogrify, according to the Transmogrification table. The mimic's size determines its hit points and the bludgeoning or piercing damage dealt by its attacks, according to the Arcane Mimics table.
The change lasts for 1 hour, until the mimic is reduced to 0 hit points, or until you dismiss the effect as an action. You can only have one mimic created in this way at a time. You can communicate with your mimic telepathically as long as it is within 120 feet of you.
In combat, the mimic takes its turn immediately after yours. It obeys your verbal or telepathic commands (no action required by you). If you don't issue any, it moves toward the nearest hostile creature and bites it if possible.
| Spell Slot Used | Maximum Size | Strength |
|---|---|---|
| 1st | Tiny | 12 (+1) |
| 2nd | Small | 14 (+2) |
| 3rd | Medium | 16 (+3) |
| 4th | Medium | 18 (+4) |
| 5th | Large | 20 (+5) |
| 6th | Large | 22 (+6) |
| 7th | Huge | 24 (+7) |
| 8th | Huge | 26 (+8) |
| 9th | Gargantuan | 28 (+9) |
| Mimic Size | Hit Points | Attack Damage |
|---|---|---|
| Tiny | 4 times the level of the spell slot used | 1d4 + the mimic's Strength modifier |
| Small | 6 times the level of the spell slot used | 1d6 + the mimic's Strength modifier |
| Medium | 8 times the level of the spell slot used | 1d8 + the mimic's Strength modifier |
| Large | 10 times the level of the spell slot used | 2d8 + the mimic's Strength modifier |
| Huge | 12 times the level of the spell slot used | 3d8 + the mimic's Strength modifier |
| Gargantuan | 20 times the level of the spell slot used | 4d8 + the mimic's Strength modifier |
Spittle Savant
6th-level Mimicry feature
Once you spend enough time in mimic slobber, you just kind of get used to it. You gain resistance to acid damage.
Additionally, you can have up to two arcane mimics created at a time. As a bonus action, you can expend a spell slot to magically heal one of your arcane mimics within 120 feet of you. The arcane mimic heals for a number of d8s equal to the level of the spell slot expended.
Polymorph Proficiency
10th-level Mimicry feature
Your knowledge of how to change creatures into mundane objects and the basic natural forms of animals is cemented in your mind. You add the polymorph spell to your spellbook if you don't already have it, and you always have it prepared. This does not count against the number of spells you can prepare at once.
When you cast polymorph, you can transform the target creature into an object instead of a beast. This object counts as magical and must be no more than one size larger than the creature. Any attempt to undo the existence of the item without reducing its hit points, such as by the disintegration spell or by using it as a consumed material component for a spell, makes the effect fail and immediately ends the polymorph effect, as if the creature-object had been reduced to 0 hit points.
You can also target a nonmagical object with this spell to turn it into another object or into a beast of the same size with a challenge rating equal to or less than the level of the spell slot used.
Mimic Mastery
14th-level Mimicry feature
You can have up to three arcane mimics created at a time, and can communicate with them telepathically or magically heal them using your Spittle Savant feature at any distance, even on different planes of existence.
