There's a fair amount of interesting magical bits and bobs in the Fantasy Battlemaps pack, but I feel it could use some more variety. In particular, here are just some thoughts on items I would particularly love to see:
Walls made of solid magical energy
An expansion on the currently available Arcane Glyphs and Summoning Circles
Standalone glowing runes and such things to apply to items
Glowing spell scrolls/spellbooks
Arcane machinery that clearly functions via magic
Wispy strands of ethereal energy
Portals that aren't explicitly hellish
