Legendary Resistance (3/Day). If the uragaraja fails a saving throw, it can choose to succeed instead.
Innate Spellcasting. The uragaraja's spellcasting ability is Charisma (spell save DC 20). It can innately cast the following spells, requiring no material components:
At will: black tentacles, detect magic, protection from energy, stoneskin, true seeing
3/day each: cloudkill, dominate person, vampiric touch, wall of fire
1/day each: imprisonment, incendiary cloud
Multiple Heads. The uragaraja has five heads. While it has more than one head, the uragaraja has advantage on saving throws against being blinded, charmed, deafened, frightened, stunned, and knocked unconscious.
Whenever the uragaraja takes 60 or more damage in a single turn, one of its heads dies. The uragaraja does not die if all its heads die but until it loses all its hit points.
At the end of its turn, it grows one head that died since its last turn. The uragaraja regains 20 hit points for each head regrown in this way unless it took radiant damage since the end of its last turn.
Reactive Heads. For each head the uragaraja has beyond one, it gets an extra reaction that can be used only for opportunity attacks.
Wakeful. While the uragaraja sleeps, at least one of its heads is awake.
Multiattack. The uragaraja makes three attacks, only one of which can be with its bite.
Bite. Melee Weapon Attack: +15 to hit, reach 15 ft., one target. Hit: 21 (2d10 + 10) piercing damage plus 14 (4d6) fire, necrotic or poison damage (the uragaraja's choice).
Tail. Melee Weapon Attack: +15 to hit, reach 20 ft., one target. Hit: 19 (2d8 + 10) bludgeoning damage and the target must succeed on a DC 25 Strength saving throw or be knocked prone.
Breath of the Cataclysm (Recharge 5-6). The uragaraja exhales unholy fire in a 90-foot cone. Each creature in that area must make a DC 23 Constitution saving throw, taking 85 (24d6) fire, necrotic or poison damage on a failed save, or half as much damage on a successful one.
The uragaraja can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature's turn. The uragaraja regains spent legendary actions at the start of its turn.
Detect. The uragaraja makes a Wisdom (Perception) check.
Tail Attack (Costs 2 Actions). The uragaraja makes a tail attack.
Snapping Jaws (Costs 3 Actions). The uragaraja makes two bite attacks.
The uragaraja is a horrific corrupted nagaraja. Where the nagaraja generally is of a bright green or dark jade with brilliant azure and golden scales the nagaraja has the color patterns of desert serpents such as a brilliant copper interlaced with crimson and black. They are ancient and come from before the time of the great Nirvana but were corrupted even before those times periods and a catalyst that caused them. These massive viper hydras dwell under the sand of shores, oasis, lakes, caves and deserts only to erupt when nomads or herds of camels are moving past and slaughter everyone and everything. If a wander encounters an entire dead caravan of nomads; people, sheep, camels, horses and all, that is probably a sign of the fallen nagarajas who take delight in bringing horror and slaughter and letting the bodies slowly rot, making it easier for digestion. Sometimes who kingdoms have collapsed from these horrific beings spreading their black and green plague clouds into the air, but the uragaraja are gluttonous and could care less, after the devour an entire town or city of dead bodies they will once again return deep into the sand to slumber for eons.
The uragaraja despise nagas, tian'lung, ryujin and phoenixes. It is an incredibly jealous creature that of all the dragons it was one of the few who were unable to fly, and it curses its luck for being bound to the earth, mentioning this to the uragaraja will send it into a seething rage and it frequently enjoys sadistically torturing slaves because of this great cosmic failure of their primordial forefather Takashaka.
Other Uragaraja enjoy dwelling in temples in corrupted civilizations, being feed by slaves especially in ancient civilizations ruled over by rakshasas such as uragas, panagas, oni and their akuma overlords. Legions of undead can be awakened by the uragaraja's necrotic breath and march forth. The corrupted naga kings love decadence and splendor and have golden jewelry and rings pierced through their thick hides. Generally, these decadent tyrants enjoy sleeping in vast sacrificial pits where they are hurled victims frequently and sleep or have conversations with their favorite slaves. Truly these beings can be charismatic and enjoy their servants' company but the servant is always hesitant when speaking because he understands that the uragaraja is simply amusing himself with his prey and playing petty mind games to manipulate others to fight amongst themselves simply for his sadistic amusement. Uragarajas have a taste for grand monuments to them and are generally pleased when massive monoliths, temples and statues are constructed in their honor. They also love watching gladiatorial combat. These beasts can be the true corrupters of human civilization. Thankfully their numbers are incredibly rare and there might be fewer than a hundred or more in the world. Additionally, they dislike their own kind and will fight savagely, sometimes devouring the loser. Occasionally they breed and bury their eggs in the deep desert sands to be heated by the scorching sunlight.
