Carapace Coffin The Leechgraves central body is protected by a 90% carapace shell that still leaves its limbs semi-exposed. Ranged attacks from physical projectiles (such as arrows made from Wood, Lead, Steel, Adamantine, ect) fired against the Leechgrave have their damage reduced by 7 points (subtracted after resistance even if it reduces the damage to 0); In the event that the weapons attack roll was a natural 19 or 20 this damage reduction is not applied.
Arcane Composter When the Leechgraves (Main Body) or (Tentaclaws) are successfully struck with an instance of Magic, make a tally mark for the the Leechgrave as a whole. This tracked feature is used for how a couple attacks scale-up over time.
(IE: A Fireball spell hitting 2x Tentaclaws + the Main Body would trigger 4 tally marks)

The base damage of this attack is 3D12 poison on a failed Con Save or half as much on a successful save. This toxin bypasses both Resistance & Immunity to Poison damage. This attack has the ability to scale up in power over the course of a battle in accordance with the tracking-marks of Arcane Composter as described in following table.
