When u do bliz4, u get those 3 stacks (arrows). Which decrease mp cost of f4 tremendously. So although not best way, I cast fire 3, then fire 4, 3 times then back to bliz3, 4...thunder, back to fire. I know I can get another fire 4,with fire 1 to add to Astral timer. But just easier and reliable not to, so I can keep Enoch going.. Once the lag goes away, I'll see about adding that extra fire. But at least the way I'm doing it, I can keep up Enoch forever... And at least if something bad was to happen during that, and lost Enoch, I still have a decent amount of mp left.
