Shadowrun: Mobile Grimoire (Sixth World Magic Cards)

The spell cards are way easier to flip through mid-run than thumbing through a rulebook, and the quick-reference format means I'm not slowing the table down looking things up. Durable enough that they've survived a few months in my bag without the corners fraying.

Keeping all the Sixth World spells on cards instead of flipping through a book mid-run has sped up our table so much. I just fan out the ones my mage knows, and combat barely slows down now.

Finally, a reference that actually respects how fast Shadowrun magic moves at the table. The quick-scan layout means I can find the right spell mid-combat without flipping through paragraphs of fluff. My group's been playing with it every session since it arrived.
