Parasitic Ichor [CARD] (Patreon)

Wondrous item, rare (requires attunement)

A viscous material that fell from the sky, this parasite forms a symbiotic relationship to those who make a connection to it, enhancing or even reforming a host’s limb as a weapon of tar and chiton. While attuned to this item you cannot remove it as it covers or replaces one of your limbs. The slick material of this item is malleable yet tough, making for a useful companion in combat. While attuned to this item your unarmed strikes deal slashing damage and it magically awakens you if you are sleeping naturally when combat begins.

Reposition. As an action you can make a ranged attack roll against a target within 30 feet of you (+6 to hit). If the attack hits, make a contested Strength check against the target. If you win the check, you pull the target towards you until it is in an unoccupied space within 5 feet of you. If you lose or the target is a strongly rooted object, you are pulled towards the target instead until you are in an unoccupied space within 5 feet of the target. If the target is a creature that is more than one size class larger than you, you automatically fail the contest and are pulled towards the target.

Second Gear. Once per long rest as a bonus action you can force your heart to beat with unnatural strength. Until you spend a bonus action to end this property or you are knocked unconscious your melee attacks gain an additional +1 bonus to attack and damage rolls, your movement speed is increased by 10 feet, and you have advantage on Dexterity checks and saving throws. When this property ends, if it was used for more than 1 minute you gain a point of exhaustion for each minute after the first.

Sentience. The ichor is a sentient, neutral evil creature with an Intelligence of 14, a Wisdom of 10, and a Charisma of 12. It has hearing and darkvision out to a range of 60 feet. The ichor can communicate telepathically with its host, and can speak through a shifting mouth in any languages its host can speak. It subscribes to a "might makes right" philosophy and as such becomes furious if its host ever abstains from violence. If angered, it may recede into its host's body and refuse to emerge (making its properties unusable) unless otherwise convinced or it feels as though it is in danger.

Though the origins of this odd, tar-like substance are disputed, its ability to enhance the combat capabilities of those it infests is much less up for debate. Granting compatible creatures great strength and agility, the side effect of having a secondary voice within one's mind seems an acceptably small price to pay for such combat prowess.
