I'm putting together a simple, fun fantasy game for my kids and I'm trying to include some magic. I am almost completely ignorant when it comes to the subject. I've got a few D&D campaigns under my belt, but I've always avoided being a caster of any kind.
We've been watching (and loving) Avatar: The Last Airbender lately and one of my favorite things about it is the way the characters use their bending abilities creatively. My hope is that I can make some general areas of magic and let the kids use their imaginations to decide how to use it, kind of like how Avatar uses Earth, Air, Fire and Water.
So, what are some spells that are used frequently in fantasy games that I can start to group into these more general areas? I'm hoping that I can get an idea of which areas would be useful and fun for the kids. I don't need an entire list of every spell ever written, just the ones that are used often or are helpful.
