" And he, what kind of training he experienced. " - Ramiel focused his gaze on another transformed skeleton. He was no match for archers, heavy-armed warriors, or spearmen.
He was a bit taller than a heavy-armed knight but slimmer. His armor also consisted of patches of bone material, but they were smaller, which translated directly into quantity. The armor also seemed lighter and less durable, but Ramiel didn't see that as a major disadvantage. Lighter armor increases mobility.
Such a solution fits more into Ramiel's fighting style. He isn't a fan of taking a hail of attacks on armor weighing a ton. He prefers light armor and relies on dodging and blocking blows rather than taking them directly.
