Silence

Khan had never suffered from mana shortage, and unlocking his new ability further eased that consumption. The symphony was his ally, allowing him to use the energy in the environment rather than his own.

That ability was incredible for many reasons. The spells' power was often below what Khan cast with his own hands. Yet, their range and flexibility were far superior, enabling unpredictable attack patterns Khan had never been able to deploy in the past.

Of course, a trade-off existed. Khan didn't really benefit from the lower mana consumption but paid the full price of the new technique anyway. The effort drained his mind, tiring him in ways normal training couldn't.

Luckily for Khan, Cegnore provided inputs that kept his mind awake, clear, and screaming. The overwhelming Nak's presence made him unable to stop, rest, or feel tired. The absolute lack of internal conflict gave birth to a fuel that pushed Khan beyond his physical limits.
