After that, Zhao Xu tried out a few more situations, and he was able to feel the boundaries of the class 'Supreme magical control.
On one hand, this class ability would increase the casting time of all his spells.
swift action would automatically change to standard action, which would then change to a full round of casting. the original full round of casting would then change to two rounds of casting.
so, even if zhao xu added spontaneous casting to most of his spells, it would only make the casting time return to normal. if he wanted to continue compressing it, he would have to rely on the subsequent spells to expand it.
On the other hand,'mental protection' was a contact spell, not a 'fixed distance' or 'self' spell, so it could not last long.
this meant that in the face of an emergency battle, zhao xu would have to first cast this spell that would last for every minute of the caster's level.
