The boulders were all made of Profound Iron Stone and were incredibly hard.
The Steel-backed Porcupines knew the danger and scattered to take cover. The ones that couldn't get out of the way simply dropped to the ground, trying to take the impact of the boulders on their backs.
The Steel-backed Porcupines' neat formation immediately dissolved into chaos. At the same time, a volley of arrows, interspersed with short spears, flew from the mountain stronghold.
In response, the Steel-backed Porcupines entered a combat stance, turning so their backs faced the stronghold.
Amid the rumbling, a cacophony of metallic clangs rang out.
After the arrow volley, apart from a few Steel-backed Porcupines that had been struck by boulders, the rest were completely unscathed.
