I’m sorry to hear that the 4-Player Upgrade didn’t include everything you were expecting. To clarify, the product description clearly states that it doesn’t include Caster Rings or Spell Clay. The product image also shows exactly what’s included: extra dice, gems, and turn-order cards to make 3-4 player games possible.
Additionally, the information can be found at the top of our FAQ and in our buyer's guide.
Including Spell Clay and Caster Rings in this upgrade would have significantly increased the size, weight, and cost of the pack. Many players already have these items from their Monster Packs, so I kept them out to keep the upgrade affordable at $15.
For those who need additional clay, you can use any brand like Play-Doh or similar options. The only requirement is starting with the same volume of clay for each army. Caster Rings can also be shared among players during a match.
I hope this helps clarify things. As for your comment about 'taking advantage of the little people,' I want to share that Necromolds is published and supported by me, an indie designer who’s passionate about creating fun and engaging games. I always strive to make Necromolds as cool and accessible as possible, and I truly appreciate you giving it a try.
