Manifestation is overpowerd.

[Sombre]

Seems like it has great balance to me. It can be countered with commander chaff, it's risky against small numbers of enemy commanders so you can't use it so much to root out raiding thugs etc, it has a high casting requirement considering it's a spell that needs to be spammed to be really painful,.. and so on. Yet it is very powerful in the right situation.
