If he has a POW of 16, say, he can do that 32 times in a day. With a Manipulation skill of 65 he can make it last 3 hours, so yes, he can keep one spell up all day excluding sleeping time. If he casts all his spells independently, he can keep up 5 spells for 18 hours a day by using all his MPs. So, I guess it is possible, but that leaves nothing left for casting any other spells. Some spells can only be cast together with Combine, though, and that reduces the duration while keeping the same MP cost.gran_orco said:I am refering that a sorcerer can do a spell like FLY or DAMAGE ENHANCEMENT many times spending only 1 mp, again, again, again...
*Edit* I'm wrong, it does leave him with most of his MPs available at any one time, but dipping into that reserve means not casting some of his regular spells in order to get those MPs back. And he might fail some of his casts as well, although it's always worth taking an extra CA or two for the +20% bonus when doing routine spell maintenance, or even taking 10 times as long for the I-can't-remember-how-big bonus.
