Today, I present to you a somewhat-larger adventure that expands on this idea! Think of this as a "proof of concept" adventure - one that includes not just Frost magic, but a small selection of hopefully interesting goodies. I think you'll most likely enjoy it

As an aside, except for the two textures you'll need to download, everything in this adventure, I believe, is vanilla, and should be able to be played even without OpenWA (although seriously you should get it if you somehow haven't already).
Oh, also, the textures go in Userdata/Custom/Objecttextures and the adventure goes in Userdata/Custom/Downloadinbox. There should be exactly three textures in the .zip attachment, which you'll need 7zip/winzip to access (though feel free to ask me if you're like me when I joined and don't know how these work xD)
Enjoy, and reach out if you're new and need any more help figuring it out! (Or if you just wanna comment on the adventure lol)
