Realizing the alarming rate at which his golems were being depleted, Ron began sending additional Scout Golems from his own dungeon. His concern was clear: if the current rate of loss continued, he'd run out of golems long before reaching the 5th floor.
The dungeon's difficulty was escalating faster than he'd anticipated, and he needed to find ways to preserve his forces.
By the time Ron's squads reached the 3rd floor, he had already sacrificed two full squads of golems. The battles and traps had taken a heavy toll, and the deeper they ventured, the longer it took to clear each floor.
The web of traps, constant ambushes by Arachnids, and the slow progress were all factors forcing him to expend more resources than he had planned.
Ron knew that the lower levels of the dungeon would be even more perilous, with longer distances to traverses the more enemies lurking.
