5E D&D Gamma World Monster: Bu'Daan (That Which Flies the Moon)

This is the latest entry in a series of creatures I converted for Fifth Edition Dungeons & Dragons to be used in my son's new Gamma World hexcrawl campaign. You can download all 150+ monsters here 

The bu’daan resembles a huge weasel with great bat wings 

A bu’daan is the master of all it surveys. This extremely rare rare creature usually lives in high areas and its fur brings an enormous price. Bu’daan are extremely territorial and feed mostly on tsorsut and yexil. However, they have been known to be cannibalistic and sometimes use their phlegm balls on each other. They generally do not eat humans or human-sized creatures, as their size hardly makes the effort worthwhile. The exception to this guideline is when a large troop of humansized creatures are traveling out in the open. The fur of a bu’daan is so thick and luxurious that it fetches an incredible price in market places, provided it is not shot up, burned, or otherwise greatly damaged and if it is no older than six days, so the tanners can properly preserve it.

ACTIONS

Multiattack.   The bu'daan makes two   attacks: one with its beak and one with its talons.

  • Beak.   Melee Weapon Attack: +15   to hit, reach 10 ft., one target. Hit: 27 (4d8 + 9) piercing damage.
  • Talons.   Melee Weapon Attack: +15   to hit, reach 5 ft., one target. Hit: 23 (4d6 + 9) slashing damage, and the   target is grappled (escape DC 23). Until this grapple ends, the target is restrained,   and the bu'daan can't use its talons on another target.

Phlegm   Ball. The bu'daan spits a glob   at a point it can see within 180 feet of it. It can use each glob only once   on a turn. A glob affects all creatures in a 45-foot radius (roll 1d4 or choose).

  • 1. Orange. All   targets are grappled (escape DC 23). Until this grapple ends, the targets are   restrained, blinded, and at risk of suffocating. In addition, at the start of   each of the target's turns, the target takes 7 (2d6) bludgeoning damage.
  • 2. Yellow. All   targets must succeed on a DC 15 Constitution saving throw or be stunned for 1   minute. The targets can repeat the saving throw at the start of each of their   turns, ending the effect on a success.
  • 3. Green. The   targets are restrained by the glob. As an action, the restrained targets can   make a DC 23 Strength check, bursting the glob on a success. The glob can   also be attacked and destroyed (AC 10; hp 5; vulnerability to fire damage;   immunity to bludgeoning, poison, and psychic damage).
  • 4. Blue. The   targets must succeed on a DC 23 Strength saving throw or be pushed up to 15   feet directly away from the bu-daan and have their speed halved until the   start of the budaan's next turn.

Lightning   Breath (Recharge 5-6). The   bu'daan exhales lightning in a 120-foot line that is 10 feet wide. Each   creature in that line must make a DC 15 Dexterity saving throw, taking 88   (16d10) lightning damage on a failed save, or half as much damage on a   successful one.
