Even with Ames's presence and use of the Sigil's Blessing, it was impossible for the Regis Elite to bridge the gap of several mage levels.
They could not gain an advantage, but they were not getting oppressed either— for short, they were in a stalemate.
Ames knew she could not allow the situation to stay that way. She might have a deep reserve of magic energy within her magic core, but they were not bottomless. True she could replenish them using the magic energies in the surroundings so that was not really a problem, but the thing was, her stamina was not the same.
Besides, The Emperor's Elite Mages and Raelia could also replenish their magic energy without any problem.
While their stamina could not hold a candle against Ames's, the fact that she, Ames, was supporting the Regis Elite, while also engaging almost all of the enemies by herself was burning her out.
