Compare the Ariadna, O-12, and Aleph Infinity d20 sets on finish, price, and faction theme to pick the metal die that matches your army.
Quick answer
Pick the Ariadna d20 if you want a worn gold finish at the lowest price, the O-12 d20 if you prefer a bright yellow-gold look and don't mind paying more, or the Aleph d20 if you want bright gold with a different faction symbol. All three share the same solid zinc alloy build and authoritative heft.
Finish and faction identity set these dice apart
The three sets differ mainly in electroplated finish and faction-specific detailing. Ariadna uses a worn gold-tone finish, while O-12 and Aleph both use a bright yellow/golden finish. That means Ariadna reads as more subdued and battle-worn, while O-12 and Aleph look brighter on the table.
Each die also carries details along the edges inspired by its army miniatures and a unique font with the faction symbol on the 1 face. If you already play that faction, the symbol makes the die easy to spot and reinforces army identity during a game.
Price differences don't buy different materials
All three are die-cast non-toxic zinc alloy with the same heft and feel. The price gap between them comes from finish and faction licensing, not from a different metal or build quality. If you are choosing purely on budget, Ariadna is the lowest-cost entry; if finish matters more, O-12 and Aleph cost more for their brighter plating.
Key trade-offs to weigh
- Worn gold vs bright gold: Ariadna's worn gold-tone finish looks more muted and may hide wear better; O-12 and Aleph use a bright yellow/golden finish that pops more under light. Choose worn gold for a low-key look, bright gold for visibility.
- Price vs finish: Ariadna is the cheapest at USD 40.79, Aleph is mid at USD 41.44, and O-12 is highest at USD 45.97. The material is the same across all three, so the extra cost is for finish and faction branding. Set a budget first; if finish is secondary, Ariadna saves money.
- Faction symbol on the 1 face: Each die has its faction symbol on the 1 face and edge details inspired by that army's miniatures. Pick the symbol that matches the army you actually play or collect. If you play multiple factions, buy the die for the army you use most.
