This set of 15 dice in Translucent Dark Purple w/ Yellow Numbers includes 3 Arch'd4, 4d6, 2d8, 2d10, d%, d12, and 2 Balance'd20. Role 4 Initiative dice average about 25% larger than traditional dice and come in a plastic display box. This popular configuration of dice is great for RPGs that can utilize multiples of the same dice in one roll, such as character generation, casting spells, or advantage/disadvantage. The Arch'd4 is a uniquely shaped die that features large top-face numbers and is easier to read, pick up, and roll. The Balance'd20 has a unique arrangement of numbers so that any 5 adjacent sides add to either 52 or 53 to ensure the most even distribution of outcomes.
