Blighted Goblin

Nimble Escape. The goblin can take the Disengage or Hide action as a bonus action on each of its turns.

Hive mind. All the blighted ones possess a hive mentality with one another. So generally, where there's one, many follow.

Blighted Spear. The Blighted Goblin wields a weapon tainted with the Blighted Scourge. Creatures struck by the spear must succeed on a DC 10 Wisdom saving throw or become infected with the Blighted Scourge (explained in the Blighted Scourge section).

Blighted Arrows (Limited Use). The Blighted Goblin can fire Blighted arrows a limited number of times. When using these arrows, creatures struck by them must succeed on a DC 10 Wisdom saving throw or become infected with the Blighted Scourge. The Blighted Goblin has a limited supply of 1d4 Blighted arrows per encounter. When out of these arrows, the goblin uses normal arrows.

Death Burst. When the Blighted Goblin drops to 0 hit points, it self-destructs in a burst of Blighted energy. Creatures within 5 feet must make a DC 10 Constitution saving throw or take 5 (1d10) Blighted energy damage and be infected with the Blighted Scourge.
