Advanced mercenary grenades bursting orange and silent, wasted on the crawlers' illusory tank formations.
New, orange-tinged explosions ripple all around Carl with a thwoom he cannot hear — he feels the strange detonations in his chest instead. He identifies them as grenades of some high-tech variety he has never seen before, brought by the offworld mercenaries rather than the dungeon-born NPCs.
They are being thrown at the Illusory Tanks, meaning the enemy's best ordnance is landing on nothing. Grenades and missiles also streak into the real assault up and down the line during the Deshrouded window, and once the crawlers reach The Craters Carl expects grenades to be raining on them at any moment.
Grenades that detonate in orange-tinged bursts, felt as chest-punching pressure more than heard.
The enemy mercenaries' advanced explosive ordnance, largely spent on decoys.
