Volt and Oka both attack the disarmed goblin and both somehow miss.
The Goblin that killed the dog looks up and, seeing the human that killed its ally, attacks. attack - (1d20+3)[21] damage - (1d4+1)[3] Unfortunately for it, it hasn't realized that attacking its flaming foe will leave it with its friend's fate. damage - (1d6)[6] The pain from the fire causes it to pass out.
Dilekar attacks and misses the disarmed goblin.
An infuriated Grum then steps up behind his oblivious prey, raises his falchion, and kills it with one stroke.
(Vellichek takes 3 points of damage, but the goblin that attacked him burns itself and is unconscious.)
