Runt grabs the Orc4 and moves to share the same position it had. Then quickly dragging the orc4 closer to the pit of fire, she throws the orc over the railings and into the fire. As the orc4, falls it's body catches fire and begins burning. The a loud thud followed by a the smell of burning flesh emanates from the pit of fire. There is no more sounds from the orc4, only the sound of crackling fire coming from the pit. While Runt stopped for a moment to catch her breath, javelin still sticking out of her stomach, Orc3 moves in behind her and tries to get her to join her latest victim in a fiery death. Runt realizes the orc3's plans and quickly kicks the would-be assassin. The kick was rushed and thus, not focused enough to do any real damage. It did however, accomplish it's goal of preventing the orc3's fire plans.
(Like the Raging Barbarian, these orcs have (NOT the fat ones or the thin ones) advantage on strength checks. Unless I misunderstood how the spell works, disadvantage from Hex cancels advantage. So the orcs have neither advantage nor disadvantage on STR checks)
(This is late, but Devarus is in the same boat as Gendan. But if the other casts need a long one, you won't hear any arguments from him at least.)
"Fiendish bastards!" Some of the calm breaks as Devarus levels the scatter at Orc3. Thinking better however, he moves as far as possible to the left to get a better position. In what effectively amounted to final spray of bolts, the lined up Orcs each receive new piercings.
