Of course, it wasn't just the old mage who was curious about Kael's spells; many mages who participated in today's battle marveled at the Rangers and the effects of the Compound Spells used by Kael.
Although to some extent, the power they could unleash far surpassed that of the Rangers, they were also clear that this ability to replicate effects on other professionals was precisely what was most precious.
If mages like Luxius, the Magic Monarch, were expanding the upper limits of magic, then Kael, by transforming the Rangers to bestow upon them greater Transcendent powers, was raising the lower limits for other professionals.
They were certainly not so foolish as to not understand such a matter.
