Woo this is awesome! I can't wait for this to come out. I can't tell you how many times I have bumped the table causing the cubes to shift and mess up my stats.
Im wondering if there will be the ability to search by type of spell like attack, conjuration etc. That's usually how I build my books. I go through each category of spells and choose from there.
If they need anymore playtesters, I would love to sign up for that!
