Oh, that's nifty! It makes it so that the Gnomes can use spells more often, but it preserves the proportions (d4 gets to use them the most, d6 the second-most, ect). And the illustrations are very fitting (especially those that incorporate the Gemstones), so it feels like a good use of time.
Thanks for directing kids toward Perch and Rescue! I run RPGs for a lot of young people in the prime Pokémon-card-collecting age group, and that interest bleeds into our games a lot, haha.
