Please note that this is designed for OG 5e (5.0, I guess, now that we've got 5.5e as an official name). I present the island shark.ISLAND SHARKSource: Homebrew.An island shark is one of the largest monsters known. It is a type of gargantuan, but even for one of those monsters, the island shark is truly on another scale. It is so big that it can consume an entire small island in a single bite. When an island shark appears in a region, the blood of the people of that region runs cold, for all know that the island shark's voracious appetites are difficult to fulfill, and the monster is so large as to be almost impossible to drive off.Too Big to Believe. An island shark is larger than entire cities that it threatens. Its maw gapes so wide that it can swallow entire islands and everything on them. The monster is so large that it is impossible to fight it as a single creature.Instead, driving off the beast requires defeating several of its body parts: one eye, its mouth, its dorsal fin, and one gill. If enough damage can be inflicted to all of these parts of its body in quick succession, it can be driven off. Even while this is being done, most creatures are so small that the shark doesn't actually engage them in combat; however, merely being close to such a behemoth is dangerous, as it continually moves, creating intense currents and other dangerous effects, bumping into nearby things as it moves, etc. Its skin is rough and abrasive, so its merest touch is dangerous.Otherwise, an island shark will eventually feed on a land mass. It is almost twenty miles long, with a gaping maw almost five miles across. It takes about a day for the shark to take a bite, but when it does, it destroys an area of the land mass about five miles in diameter and roughly spherical in shape, killing or swallowing whole every living thing on it.An Internal Nightmare. Creatures swallowed might be able to escape, but the island shark's belly and innards almost always contains its own ecosystem full of predators, including smaller sharks, aquatic oozes such as bloodbloater swarms, blue slimes, flotsam oozes, and sometimes even communities of aquatic folk such as sahuagin, locathah, mermaids, or avanti).Often, the interior of an island shark has some sort of terrible monster that serves as an apex predator. Even something as large as a giant shark, ooze octopus, or the like might hunt the flooded passages within an island shark.A Lair for Mighty Recluses. There have been several occasions where powerful individuals intentionally got swallowed in order to lair within an island shark. Whether seeking isolation or adventure, creatures such as a shou lung, dragon turtle, lich, and a renegade githyanki knight of surpassing ability have hidden themselves away inside of an island shark. By doing so, they render themselves accessible only to those daring enough to face the island shark and to accept the risk involved in being swallowed.Island Shark Treasure. An island shark doesn't collect treasure, but its gut can contain entire civilizations' worth of loot. Such treasure is inevitably taken up by the creatures that live inside the shark, however.Creatures living inside an island shark get a +25% bonus to their chances of having treasure. In addition, they have double the normal amount of treasure.Island Shark EyeGargantuan Beast (Gargantuan, Shark), always unalignedArmor Class 15 (natural armor)Hit Points 512 (25d20+250)Speed 0 ft., swim 90 ft. STR 30 (+10), DEX 10 (+0), CON 30 (+10),INT 3 (-4), WIS 12 (+1), CHA 6 (-2) Condition Immunities charmed, deafened, exhaustion, frightened, grappled, paralyzed, petrified, poisoned, prone, restrained, unconsciousSenses blindsight 100 miles., passive PerceptionLanguages -Challenge 23 (50,000 xp) Prof +7 Part of a Greater Whole.
