That's a great idea! Do you mean beams like a spell/attack that's cast in a direction (kind of like a lazer gun type of thing), or beams that hit the ground?
I've planned for the next pack to be free magic projectiles, so the lazer gun style beams could fit into that pack. If you mean more in line with a beam that hits the ground and is kind of more like the ones on this pack, then I'll work on an update once the next pack is released!
Or maybe I could do a seperate beam themed pack. What so you think?
