Kayang/Pennaggolan Shogun (5e Creature)
From D&D Wiki
Medium undead (shapechanger), neutral evil
Saving Throws Dex +10, Wis +9, Cha +9
Shapechanger. If the kayang isn't in sunlight or running water, it can use its action to polymorph into a Small or Medium humanoid, a Medium or smaller beast, a Medium cloud of mist, or back into its true form.
Legendary Resistance (3/Day). If the kayang fails a saving throw, it can choose to succeed instead.
Rejuvenation. If it has a phylactery, a destroyed kayang gains a new body in 1d10 days, regaining all its hit points and becoming active again. The new body appears within 5 feet of the phylactery.
Regeneration. The kayang regains 20 hit points at the start of its turn if it has at least 1 hit point and isn't in sunlight. If the kayang takes radiant damage, this trait doesn't function at the start of the kayang's next turn.
Spider Climb. The kayang can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.
Kayang Weaknesses. The kayang has the following flaws:
Cantrips (at will): mage hand, prestidigitation, ray of frost
Multiattack (Kayang Form Only). The vampire makes three attacks, only one of which can be a bite attack.
Entrails (Kayang Form Only). Melee Weapon Attack: +16 to hit, reach 15 ft., one target. Hit: 13 (1d6 + 10) bludgeoning damage. Instead of dealing damage, the kayang can grapple the target (escape DC 22).
Bite (Kayang Form Only). Melee Weapon Attack: +16 to hit, reach 5 ft., one willing creature, or a creature that is grappled by the kayang, incapacitated, or restrained. Hit: 13 (1d6 + 10) piercing damage plus 10 (3d6) necrotic damage. The target's hit point maximum is reduced by an amount equal to the necrotic damage taken, and the kayang regains hit points equal to that amount. The reduction lasts until the target finishes a long rest. The target dies if this effect reduces its hit point maximum to 0. A humanoid slain in this way and then buried in the ground rises the following night as a vampire spawn under the kayang's control.
Greatsword (Kayang Form Only). Melee Weapon Attack: +16 to hit, reach 5 ft., one target. Hit: 17 (2d6 + 10) slashing damage. This is a magic weapon attack.
Charm. The kayang targets one humanoid it can see within 30 feet of it. If the target can see the kayang, the target must succeed on a DC 17 Wisdom saving throw against this magic or be charmed by the kayang. The charmed target regards the kayang as a trusted friend to be heeded and protected. Although the target isn't under the kayang's control, it takes the kayang's requests or actions in the most favorable way it can, and it is a willing target for the kayang's bite attack.
The kayang 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 kayang regains spent legendary actions at the start of its turn.
Move. The kayang moves up to its speed without provoking opportunity attacks.
The kayang were once powerful warlords in life who gained some form of immortality through dark magic. They have been witnessed being decapitated and disembowled only to be seen again with a large scare from where the wound was unless the head and body are both destroyed by fire, traditionally on two different funeral pyres. The kayang is famous for mixing spells and weapon strikes, as they know the arts of wizards.
Undead Nature. A kayang doesn't require air, food, drink, or sleep.
