Reaper King (5e Creature)
From D&D Wiki
Huge aberration, unaligned
Powerful Legs. The reaper king has a standing high jump of 80 feet, and a standing long jump of 110 feet.
Dark Stalker. The reaper king reduces damage dealt to it by 10, before resistance. This and it's resistance to non-magical damage is ignored if it is in bright light.
Multiattack. The reaper king makes one bite attack and one tail attack. If it makes a tail spines attack, it can make a bite attack if it is currently grappling a creature with it.
Bite. Melee Weapon Attack: +12 to hit, reach 10 ft., one target. Hit: 38 (5d12 + 8) piercing damage. If the target is a Medium or smaller creature, it is grappled (escape DC 17). Until this grapple ends, the target is restrained, and the reaper king can't bite another target.
Tail. Melee Weapon Attack: +12 to hit, reach 10 ft., one target. Hit: 24 (4d8 + 8) slashing damage.
Tail Spines. The reaper king launches a hail of spikes from it's tail. Everything in a 60 ft. cone from the reaper king must make a DC 16 Dexterity saving throw, or take 18 (4d8 + 2) piercing damage, and have their movement speed reduced by 25 ft until the start of their next turn.
The reaper is akin to a alien tyrannosaurus rex, by both definitions of the word. An incredible hunter in the wild, it's versatility is second to none. While it is fully capable of ambushing it's prey through burrowing, it can also easily weather a head-on assault against just about anything else in the wild, being massively durable and violently inclined. This durability seems to wain when exposed to light, particularly bioluminescence. It hates it, and while it does seek to avoid it, not much will deter it from seeking other prey. Should one be crazy enough to seek out a reaper, one must go deep underground, normally to a highly irradiated area.
Reapers have a big case of Sexual Dimorphism. Males, aka Reaper Kings, are armored and are incredibly aggressive, but are also more common. Females, aka Reaper Queens, are larger than Kings and have more vibrant displays, while also being able to tranquilize targets. Reapers have an unorthodox method of breeding, the Queens throw egg pods out of their tails, and then these eggs impact the victim and inject the fetal Reaper into the Host. The Reaper larva slowly grows, causing host to feel unnatural or excessive fatigue, minor swelling of certain body parts, Nausea without vomiting, and fevers for a while. This continues until the larva burrows out of the host, often killing it. Then the Reaper scuttles off into the darkness and matures into an adult reaper.
