Hmm, everybody pretty much hit the nail on the head. Some spells are rediculusly hard (Undine), while others are pretty easy (Silent Selina, the safespot is hard not to use).
Earth sign "Surrounded by All Sides" was my favorite spell, followed by Moon Sign "Silent Selina". At least on Phantasm mode, Silent Selina is pretty difficult and looks badass.
I did enjoy playing this script, even though I think some spells have too much health (they get kinda dragged out and boring after a while). Hope to see more from you in the future.
