spells in the shop, green highlighted are spells i care about and would almost always buy if i saw them
teleport - obvious
long distance cast - has a multitude of uses but ill show you a quick one right here in the webm. free shop exit
yellow are situationally useful
holy lance - little known fact that this can actually dig brickwork in a pinch
light - you can use this as a 1 mana spell wrapping tool if you have nothing else and the light itself is useful in some cases
delayed spellcast - has its uses. mainly for something that beginners have no idea about and im not going to discuss because it will break your mind (seriously dont worry about it its not important and will not help you)
