Stench. Any creature that starts its turn within 5 ft. of the ghast must succeed on a DC 10 Constitution saving throw or be poisoned until the start of its next turn. On a successful saving throw, the creature is immune to the ghast's Stench for 24 hours.
Turning Defiance. The ghast and any ghouls within 30 ft. of it have advantage on saving throws against effects that turn undead.
Actions
Bite. Melee Weapon Attack: +3 to hit, reach 5 ft., one creature. Hit: 12 (2d8 + 3) piercing damage.
Claws. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 10 (2d6 + 3) slashing damage. If the target is a creature other than an undead, it must succeed on a DC 10 Constitution saving throw or be paralyzed for 1 minute. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
How many ghasts for a fight?
A ghast is worth 450 XP. Using the 2024 encounter budgets (SRD 5.2), this is how many ghasts fit each difficulty for a party of four characters of the same level. A dash means even one would be over the budget.
