These fighters use mimics to their gain, as a mimic warrior might wield a shield that is a mimic, or a mimic great sword. These fighters make deals with mimics to feed them if the mimics will aid them is combat, and consequently some mimics actively seek them out.

Mimic Weapons

You gain a mimic that shapes itself into a piece of gear for you to use. You gain an additional piece of mimic gear whenever you get an ability score improvement, with the exception of level four.

The options are as follows:

Simple melee weapon: Whenever you strike with this weapon, you deal additional acid damage equal to 1d4 plus your proficiency bonus. 

Martial melee weapon: your range with this weapon is 10 ft. greater than normal, and the weapon gains +1 to attack and damage rolls. The bonus increases to +2 at level 7, and +3 at level 13.

Simple ranged weapon: The weapon launches acid, dealing acid damage rather than the normal type, and the target must succeed on a DC (10+prof bonus) Con save or become poisoned until the start of your next turn.

Martial ranged weapon: A creature hit by this weapon is pulled 30 ft. straight toward you by the mimics tongue. If the creature reaches you during this movement, it becomes grappled and you may use a bonus action to make a melee weapon attack against said creature.

Shield: If an attack roll misses you by less than 3, you may use your reaction to grapple the creature and deal 2d4 plus your proficiency bonus acid damage.

Light armor: When you are hit by a melee attack roll, you may use a reaction to have the armor bite the instigator. Make a melee weapon attack that you are proficient in, dealing 1d10 plus your proficiency bonus piercing damage on a hit.

Medium armor: You have advantage on checks made to grapple a creature, and gain advantage on attack rolls against grappled creatures. 

Heavy armor: When you are hit by a ranged attack roll, you may use your reaction to reduce the damage taken by 2d6, as the mimic eats the projectile. If the damage is acid or poison, the reduction is doubled. If the damage is psychic or necrotic, the reduction is halved. 

 

Vocal Mimicry

If you have heard a creature speak for at least one minute in a language you know, you can perfectly imitate their voice while speaking that language.

Blessing of the Mimics

You can cast alter self on yourself at will. Additionally, when you cast alter self this way you can make yourself look like an object of you same size or one size smaller. A creature investigating said object discerns it is you by succeeding on an insight check contested by your deception or stealth check.

Mimic’s Pact

If you are not attuned to any magic items, your AC increases by 2, and you can change your size at will. Additionally, wearing heavy armor no longer imposes disadvantage on dexterity. When a creature touches you it automatically becomes grappled. 

Mimic King

Attacks against grappled creatures are always crits. You cannot voluntarily end a grapple.
