Sinii Krai (5e Creature)
From D&D Wiki
Large dragon, chaotic neutral
Saving Throws Dex +9, Con +8, Wis +5, Cha +9
Amphibious. The Sinii Krai can breathe both underwater and on land.
Charge. If the Sinii Krai moves at least 20 feet straight toward a creature and then hits it with a claw attack on the same turn, that target must succeed on a DC 16 Strength saving throw or be knocked prone. If the target is prone, the Sinii Krai can make one bite attack against it as a bonus action.
Naturally Poisonous. The Sinii Krai's skin secretes a highly lethal poison, and it is imperative that you do not touch it for any reason. Any creature that makes physical contact with the Sinii Krai's skin must succeed on a DC 17 Constitution saving throw, taking 40 (8d8) poison damage on a failed save, and half as much damage on a successful one. If this feature reduces a creature to 0 hit points, the toxin will spread throughout its whole body and render it delirious, causing the creature to have disadvantage on death saving throws.
Rampage. When the Sinii Krai reduces a creature to 0 hit points, with a melee attack on its turn, the Sinii Krai can take a bonus action to move up to half its speed and make a melee attack.
Sure-footed. The Sinii Krai has advantage on rolls against being knocked prone.
Territorial. Sinii Krai are very prideful and territorial dragons. If a Sinii Krai notices a creature encroaching upon its territory, it will not hesitate in chasing it off or killing it. The Sinii Krai will pursue a creature until it has run 120 ft. away in the opposite direction.
Multiattack. The Sinii Krai makes three attacks: one with its bite, and two with its claws.
Bite. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 14 (2d10 + 4) piercing damage and 4 (2d4) poison damage.
Claw. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 12 (2d6 + 4) slashing damage and 4 (2d4) poison damage.
Unbridled Fury. In response to being hit by a melee attack, the Sinii Krai can make one melee weapon attack with advantage against the attacker.
The Sinii Krai can take 2 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 Sinii Krai regains spent legendary actions at the start of its turn.
Detect. The Sinii Krai makes a Perception check.
The Sinii Krai ("Blue Edge" - Russian transliteration) is a relatively small species of dragon that can be found anywhere with easy access to coastlines and other large bodies of water. They love all types of seafood, but fish are their absolute favorite.
Though they are incredibly vibrant and beautiful, they are nearly impossible to tame - half because of their temperament, and half because of their toxic skin. They make up for their lack of a breath weapon with their quite lethal poison, which is imbued in every attack they make. Also, they have very strong personalities, are extremely noisy, and do not take well to the domestic lifestyle.
Individually, the Sinii Krai is not too formidable of an enemy for a band of experienced adventurers. However, Sinii Krai are almost never alone. As a matter of fact, they tend to live in groups of 10 or more. Even the greatest warriors avoid going near known Sinii Krai grounds, as a group of Sinii Krai can easily overwhelm and slaughter most people. It's considered suicidal to go up against any number of Sinii Krai without being covered head-to-toe in poison-resistant gear.
