Rajang (5e Creature)
From D&D Wiki
Huge beast, unaligned
Saving Throws Str +15, Con +16, Wis +12
Golden Rage. Whenever the rajang starts its turn with 130 hit points or fewer, it enters a golden rage. While in a golden rage, it has advantage on melee attack rolls and deals an additional 6 (1d12) lightning damage whenever it hits with a melee attack (included in the attack).
Severed Tail. If the rajang takes 70 or more slashing damage at one time, its tail is severed. While its tail is severed, it can't use its Golden Rage. The rajang grows a new tail when it finishes a long rest.
Multiattack. The rajang makes two fist attacks.
Fist. Melee Weapon Attack: +15 to hit, reach 5 ft., one target. Hit: 34 (4d12 + 8) bludgeoning damage and 6 (1d12) lightning damage if the rajang is in a golden rage.
Lightning Beam (Recharge 6). The rajang exhales lightning in a 90-foot line that is 5 feet wide. Each creature in that line must make a DC 24 Dexterity saving throw, taking 66 (12d10) lightning damage on a failed save, or half as much damage on a successful one.
Unbridled Fury. In response to being hit by a melee attack, the rajang can make one melee weapon attack with advantage against the attacker.
The rajang 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 rajang regains spent legendary actions at the start of its turn.
Move. The rajang moves up to its speed.
The imposing, solitary rajang is a massive horned ape and the master of the mountains it calls home. Only the most powerful of creatures can even stand a chance against a rampaging rajang, which defends its chosen territory fiercely. On the rare occasion that the rajang encounters a foe that can truly pose a challenge, the fur covering its entire body turns golden and it enters a terrible rage in which it somehow becomes even more dangerous. If the rajang's tail is severed, it can't use this ability and is returned to its original state.
Always Solitary. Thankfully, rajangs are always encountered alone. There has never been a report of more than one rajang being encountered at the same time, or even on the same mountain. This has raised questions about how they reproduce, but none who have tried to find those answers have ever returned. According to one theory, a rajang emerges from a stone egg that has become imbued with the energies of heaven and earth over centuries.
