Big Bad Glinblin

Aggressive. As a bonus action, the glinblin can move up to its speed toward a hostile creature that it can see.

Multiattack. The glinblin makes two acid sword attacks.

Bite. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 15 (1d10 + 2) piercing damage the creature hit makes a constitution saving throw DC 13 if they fail they take (1d12 + 6).

Slam. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 5 (1d6 + 2) bludgeoning damage.

Acid Infused Sword. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 9 (1d12 + 3) slashing damage the creature hit makes a constitution saving throw DC 13 if they fail they take (1d12 + 6).

Javelin. Melee or Ranged Weapon Attack: +5 to hit, reach 5 ft. or range 30/120 ft., one target. Hit: 6 (1d6 + 3) piercing damage.

Horrible Smell. If a living creature with a sense of smell that is not an orc, goblin, or glinblin comes into combat with the big bad glinblin they must make a constitution saving throw DC 10 or they take (1d6).

Pounce. If the glinblin moves at least 30 feet straight toward a creature and then hits it with a claw attack on the same turn, that target must succeed on a DC 13 Strength saving throw or be knocked prone. If the target is prone, the glinblin can make one bite attack against it as a bonus action.

Acid Blood. I value GM decision making but the big bad glinblin has large amounts of acid in its bloodstream so if you wish and a player chooses to touch its blood or they fail a roll of your choice they suffer (1d6).

Acid Breath (Recharge 5–6). The glinblin exhales acid in a 5-­foot line that is 5 feet wide. Each creature in that line must make a DC 18 Dexterity saving throw, taking 4 (1d8) acid damage on a failed save, or half as much damage on a successful one.

Innate Spellcasting. The glinblin’s innate spellcasting ability is Intelligence (spell save DC 11). It can innately cast the following spells, requiring no material components:

At will: acid splash

1/day each: poison spray
