I love the slightly-oversized dice from Role 4 Initiative, so I just ordered a new set for use with Cortex Prime. Quite affordable — only $0.63 per die. I am using different colors for each die type to make it easy to differentiate at the table (and also its great for players new to RPGs who have trouble telling a d10 from a d12, etc.). I’m using Purple for d4s, Green for d6s, Blue for d8s, Red for d10s, and Black for d12s. I’m red-green color blind but these shades are bright and distinct enough even for me to tell apart. Can’t wait to use them in my upcoming Cortex Plus campaign!
