Nuckelavees are a possible Evolution of Infected Adventurers, belonging in the Evolved tier. They are fast and capable melee combatants.
Spawning
Evolved from an Infected Adventurer when it obtains at least 1 Evolution Point and its 5 minute Evolution timer expires. Once it does, it has a 22.5% chance to Evolve into a Nuckelavee.
Can be spawned by Challenge Watchers during the third wave and above of a Challenge Raid.
Can be spawned by Vigils during the second wave of a Vigil Raid.
Unique Behavior
Nuckelavees are capable of visibly wearing Armor in all possible slots. When a Nuckelavee Evolves naturally from an Infected Adventurer, it will keep any Armor and items the Infected Adventurer wore/held. When a Nuckelavee spawns via any other means, it'll retain the same values as Infected Adventurers do for spawning with Armor, items, and a name.
Nuckelavees are capable of using Bows, Flint and Steel, and Shields (this is in addition to Melee Weapons).
When wielding a Bow, Nuckelavees will attempt to stay at a distance of 20 blocks from their current target while shooting arrows every 2.5 seconds, said arrows being tipped with Mycelium Infection I for 30 seconds. If their current target gets within 10 blocks, they'll switch to dealing melee damage.
When wielding Flint and Steel, Nuckelavees will set targets on fire for 10 seconds when dealing melee damage.
When wielding a Shield, Nuckelavees have a 35% chance to block any incoming damage (projectiles are deflected). This does not stack with multiple Shields.
When a Nuckelavee kills an entity, if said entity was holding a Melee Weapon that deals more damage than the Nuckelavee's current main slot item or was wearing any Armor that provides more armor value than what's in the corresponding armor slot of the Nuckelavee, then the Nuckelavee will steal the Melee Weapon/Armor upon the entity's death and replace its old item/Armor with it. If the Nuckelavee had nothing in its main hand slot/corresponding armor slot, it'll steal it like normal.
Nuckelavees have 1.0 knockback resistance, meaning they can't be knocked back by attacks.
Nuckelavees have a step up height of 1, meaning they don't have to jump to go up blocks that are 1 block tall.
Used to obtain Skeletal Blood Samples via Syringes.
