D6 vs Polyhedral Sets: Which Dice Set Should You Buy First?

Quick Answer

If you are starting Dungeons & Dragons or any d20-based RPG, buy a polyhedral dice set first because it covers every roll the game asks for. Choose a D6 set first only if you mainly play dice-pool games, wargames, or board games that use six-sided dice. Many players eventually own both, but your first purchase should match the game you play most.

The D6 versus polyhedral question comes up because both sets look like dice, but they serve different games. A D6 dice set is built around six-sided dice, while a polyhedral dice set spreads across seven shapes. Buying the wrong one first means missing rolls at the table or paying for dice you never pick up.

This comparison uses the actual sets in the Dispel Dice catalog to show what each type does well, where each falls short, and which one makes sense as a first purchase. If you want the short version: match the set to your game system, not to the prettiest finish.

What Each Set Actually Contains

A polyhedral dice set covers the full range of shapes used in D&D and similar RPGs. The Rosewindow 7-Piece Iconic Dice Set includes one D4, D6, D8, D10, D%, D12, and D20, so a single purchase handles attack rolls, damage, saving throws, and percentile checks. That completeness is the main reason polyhedral sets are the default recommendation for new D&D players.

Rosewindow 7-Piece Iconic Dice Set

A D6 set, by contrast, is a collection of six-sided dice. The Dispel x Eat the Reich 2-Set Bundle contains two 4-piece Iconic D6 sets, giving you eight D6 dice total across two themed designs. That is a lot of six-sided dice, but no D20, which matters if your game expects one.

Dispel x Eat the Reich 2-Set Bundle

• Check your rulebook's dice list before buying. If it names a D20, you need a polyhedral set.
• If your game only calls for D6 pools, a D6 set avoids unused shapes.

Where D6 Sets Win

D6 sets shine in games that resolve actions by rolling pools of six-sided dice. The Dispel x Eat the Reich 2-Set Bundle is a good example of this use case: two 4-piece Iconic D6 sets themed after the neon nightmare of fictional 1940s France, giving you enough dice to roll several at once without passing a single die around the table.

Six-sided dice are also the most familiar shape for players coming from board games and wargames. If your group already owns a pile of D6s from other hobbies, adding a themed D6 set is an easy upgrade that fits what you already play.

• Count the maximum dice your game asks you to roll at once, then buy at least that many D6s.
• A themed bundle gives you two looks at the table, which helps separate pools or factions.

Where Polyhedral Sets Win

Polyhedral sets win on coverage. The Harlequin 7-Piece Iconic Dice Set follows the same seven-shape formula as the Rosewindow set, so it works for any d20-based campaign without adding extra purchases. If you are buying dnd dice for beginners, this is the safer category because it removes the risk of missing a shape mid-session.

Polyhedral sets also carry more visual variety per purchase. The Death By Ooze 7-Piece Iconic Glow in the Dark Dice Set uses foil silhouettes and a neon glow-in-the-dark core, while the Aurora Borealis 7-Piece Iridescent Dice Set uses a transparent iridescent shell. Either one gives you seven distinct dice in a single theme, which reads clearly on the table.

• Sharp-edged construction, used across these sets, allows for more randomized rolls than traditional rounded-edge RPG dice.
• If you only buy one set, make it polyhedral and add D6s later.

The Trade-Off in Plain Terms

The core trade-off is coverage versus focus. A polyhedral set gives you every shape a d20 game needs, but if you mostly play dice-pool games, several of those shapes will sit unused. A D6 set gives you depth in the shape you roll most, but it cannot substitute for a D20 in D&D.

There is also a cost angle worth noting. In the supplied catalog, the Aurora Borealis and Celestia 7-Piece Polyhedral Dice Sets are priced at USD 35.00, while the Rosewindow, Harlequin, and Death By Ooze sets are USD 42.50. The Dispel x Eat the Reich 2-Set Bundle is USD 47.50 for two D6 sets. Compare what you get per usable die, not just the sticker price.

• If your game uses both D6 pools and a D20, a polyhedral set plus a small D6 add-on is the most flexible path.
• Do not buy a D6 set as your only purchase for a d20 system.

Trade-Offs at a Glance

• Coverage vs. depth: Polyhedral sets cover every standard shape but may leave some dice unused in D6-only games. D6 sets give you many six-sided dice but no other shapes. Buy polyhedral first for d20 systems; buy D6 first for dice-pool games.
• Price per usable die: Polyhedral sets in the catalog run USD 35.00 to USD 42.50 for seven dice. The Dispel x Eat the Reich 2-Set Bundle is USD 47.50 for two 4-piece D6 sets. Compare against the dice your game actually uses, not the total count.
• Visual consistency: A single polyhedral set keeps one theme across all seven shapes. A bundle gives you two D6 themes, which can help separate pools but does not add new shapes. Choose based on whether you need shape variety or dice quantity.

Catalog Facts That Affect Your Choice

• Rosewindow 7-Piece Iconic Dice Set: Includes one D4, D6, D8, D10, D%, D12, and D20, with sharp-edged construction for more randomized rolls than traditional rounded-edge RPG dice. This is the complete shape range for D&D, so one purchase covers every standard roll in a d20 campaign.
• Harlequin 7-Piece Iconic Dice Set: A 7-piece set with gold foil and vintage color illustrations on an ivory core with matching matte numbers. If you want full polyhedral coverage with a distinctive look, this set delivers the same seven shapes in a different visual style.
• Death By Ooze 7-Piece Iconic Glow in the Dark Dice Set: A limited edition 7-piece set with foil silhouetted swords, shields, and magical items and a neon glow-in-the-dark core. Good for players who want their polyhedral set to stand out at the table, especially in dim play spaces.
• Aurora Borealis 7-Piece Iridescent Dice Set: A 7-piece polyhedral set with a transparent iridescent shell and warm mylar, part of the Iridescence Collection. A lower-priced polyhedral option at USD 35.00 that still covers all seven standard shapes.

Which Should You Buy First?

Buy a polyhedral set first if you:

• Play Dungeons & Dragons or another d20-based RPG and need every standard shape
• Are buying dnd dice for beginners and want one purchase that covers all rolls
• Want a themed set like Rosewindow or Harlequin that works across most campaigns

Buy a D6 set first if you:

• Mainly play dice-pool games, wargames, or board games that use only six-sided dice
• Already own polyhedral dice and want more D6s for large pools
• Need a themed gift for a player whose game never calls for a D20

Start with the set that matches your rulebook. For D&D and similar RPGs, a polyhedral set like Rosewindow or Harlequin is the practical first buy. For dice-pool games, the Dispel x Eat the Reich 2-Set Bundle gives you the six-sided dice you will actually roll. Add the other type later once you know what your table needs.
