Purchase this D20 booster pack to supplement your D20 collection. There are times when the single D20 from your set seems inadequate.
Perhaps you're about to roll a critical skill check with advantage and you want two dice that are intrinsically linked to help give you that extra mojo you need to succeed?
The Chaos and Law D20 booster set is just the thing.
Like the ying and yang of Dungeons and Dragons, Chaos and Law are presented here in perfect synergy.
