Grezk, the Drainer of Giants

In the right season, in most warm and humid climates, one may find ticks and, if one is unlucky, giant ticks. Then there is Grezk, the Drainer of Giants, a tick much larger than the giants of its name. Many who fight Grezk, the Drainer of Giants are so horrified by the discovery that such a thing exists that they are scarcely willing to fight.

Patient Parasitism. One would not expect something this size to be able to hide, but its ability to climb and drop down on victims, pinning them down as it drains them, changes the matter. As Grezk, the Drainer of Giants exsanguinates its targets, it fills their veins with disease in return.

Mindless Servant. Grezk, the Drainer of Giants has no appreciable will of its own, but serves a hidden master. Whoever that master may be, they collect blood from Grezk, the Drainer of Giants – both to keep it hungry, and to serve their own dire purposes.

Special Traits

  • Colossal Creature. Kaiju are creatures far larger than the scale of others. Conventional weapons, even highly-enchanted ones, lack the mass to deal serious wounds to a kaiju. The same is true for all but the mightiest spells. When a creature of Huge size or smaller deals damage to a kaiju with a weapon or feature, or with a spell of 8th level or lower, its damage is halved, and can be reduced further by resistance or saving throws. Siege weapons and creatures with the Siege Monster trait are treated like Gargantuan creatures. Creatures of size Huge and smaller can move through or occupy a kaiju’s space. Gargantuan creatures and 9th-level spells (including lower-level spells cast with 9th-level slots) deal normal damage, which can be reduced further by resistance or saving throws. Kaiju deal double damage to objects and structures. They ignore normal difficult terrain, and treat thick forests, settlements, or mountains as difficult rather than impassable terrain.
  • Legendary Resistance (3/Day). If Inu fails a saving throw, it can choose to succeed instead.
  • Latch On. Grezk, the Drainer of Giants has advantage when rolling Strength (Athletics) checks to grapple.

Actions

  • Bite. Melee Weapon Attack: +10 to hit, reach 20 ft., one target. Hit: 33 (6d8 + 6) piercing damage, and the creature must make a DC 16 Constitution saving throw. On a failure, it contracts sewer rot. If the target loses hit points from this attack, it is grappled.
  • Bloody Spittle. To use this ability, Grezk, the Drainer of Giants must have affected a creature with its Blood Drain trait within the last minute. Grezk, the Drainer of Giants spits acidic blood in a line 5 ft. wide and 100 ft. long, or in a cone 50 ft. long. Creatures in the area must roll DC 16 Dexterity saving throws. On a failure, they suffer 21 (6d6) acid damage and are blinded until the end of their next turn; on a successful save, they take half that amount of damage and are not blinded.

Legendary Actions

Grezk, the Drainer of Giants can take 3 legendary actions, choosing from the options below. Only one legendary action can be used at a time and only at the end of another creature’s turn. Grezk, the Drainer of Giants regains spent legendary actions at the start of its turn.

  • Bite. Grezk, the Drainer of Giants makes one bite attack.
  • Blood Drain. If Grezk grapples a creature that isn’t a construct or undead, the creature takes 27 (6d8) necrotic damage. The target’s hit point maximum is reduced by an amount equal to the necrotic damage taken. The reduction lasts until the target finishes a long rest. The target dies if this effect reduces its hit point maximum to 0.
  • Recover. Grezk, the Drainer of Giants regains 50 hit points. Once it uses this ability, it can’t do so again until the end of its next turn.
