The standard set of 7 polyhedral dice is the bare minimum. It should include dice with four, six, eight, twelve and twenty sides as well as two with ten sides (one will be numbered 1 to 10, the other 00 to 90). Depending on what class you play you might want to get some extra dice for damage rolls.
How many D6 do you need?
The only die that you really need more than one of is the humble d6. d20 – handy to have two, so you can roll attacks or checks with advantage/disadvantage. d12 – only need one.
Why does a d10 have a 0?
The one with two digits is just telling you the tens digit, and the one with one digit is the ones digit. If you’re rolling only that die with 0, 10, 20, etc., then a 10 = a 1 and the 00 = a 10. 0 or 00 on a d10 just means the highest number.
Should I buy more dice?
The more dice you have on hand, the faster you can get rolls done which keeps the game flowing. My players most often use d4s or d6s for damage dice – most have a bag each. If they need more dice, such as 8d6 for a spell, I have a stockpile of different dice I can lend to them for the session.
Why are dice so expensive?
They cost more, not just because they use more material, but also because few factories are set to make them. They are a niche product, even within the niche that polyhedral dice are already in.
Why do D&D players have so many dice?
It serves as a form of social reinforcement for the dice. If the dice roll poorly, they can be shamed in front of their peers. If the dice roll well, then they earn the respect and adulation of the other dice.
Can you play D&D by yourself?
Yes, it’s quite possible and can actually be very fun. The ideal situation is for a small group of people to play with a story teller (DM) and players, but you can play D&D alone, with just a buddy or a few people without a DM or with a full group. There are even modules and apps that are dedicated to this pursuit.
