Which consequence increased the risk of deploying Roman torsion siege weapons during prolonged sieges in humid coastal environments?

💡 Explanation

When subjected to humidity, the ropes of torsion siege engines like the ballista absorbed moisture of humic air, therefore rope fibers swelled, reducing torsion spring force leading to loss of projectile velocity hence decreased range. Therefore decreased range resulted, rather than fractures, inaccurate targeting or slower deploy which are unrelated and driven by independent environmental phenomena.
