  • Dice tray

    A lidded tray keeps rolls off the character sheet. The Basic Rules do not require one. Buy it with dice, not with sleeves.

  • Dice tower

    A tower drops a roll down baffles onto the tray. Habit, not a rule. Skip it until the dice set exists.

Left off this cluster

Card sleeves, playmat, and deck box. Those are card-deck tools. If the table is TCG, open the sleeves kit. If you still do not know, open the starter kit.
