A mass of mechanical constructs the Reavers rigged with proximity-triggered satchel charges to blast a funnel into Carl's base.
Under cover of the smoke on the barracks battlefield, the enemy gathers a ton of automatons at the far right corner, each fitted with Explosive Satchels on a proximity trigger. Carl's trap sense catches them and his advanced Find Trap skill enumerates them in a cascade of info boxes. Checking his map, he confirms that half of the field holds only purple enemy dots and a few reanimated mages.
He casts Tripper and the entire cluster goes up at once. The area where the automatons had been gathered is reduced to a crater, and every Reaver Security Force Cyborg Drop Trooper near them is simply gone. The blast knocks down nearly everyone on both sides and rains scorched metal onto the barracks roof.
Mechanical constructs bristling with strapped-on satchel charges, their arming lights glaring through the battlefield smoke.
The enemy's walking demolition charges, destroyed before they could be used.
