This specialized die features Chessex’s innovative Countup&down™ numbering system, designed to make incremental tracking faster, clearer, and more intuitive than ever.\nUnlike standard d20s, each face on a Countup&down™ die includes a small directional indicator pointing toward the next highest number. When the die is placed on the table—number facing upward—the next number in sequence will always appear directly beneath it, allowing for effortless turn counting, HP tracking, spell duration management, or any system requiring sequential increments.\nIn addition to its functional design, this model features a striking ivory white base with vivid green numerals, a prototype colorway not available in regular production. At 25mm from face to face, it’s significantly larger than the traditional 18mm Chessex d20, giving it bold tabletop presence and easy readability.\n⭐ Key Features:\n\n\n\nCountup&down™ directional numbering for seamless tracking\n\n\nIndicators on each face show the next number in sequence\n\n\nOversized 25mm d20 (larger than standard 18mm Chessex d20s)\n\n\nIvory White/Green limited-edition prototype colorway\n\n\nPerfect for:\n\n\nTurn counters\n\n\nHit point or mana tracking\n\n\nSpell duration or round tracking\n\n\nBoard games, TTRPGs, and custom systems\n\n\n\n\nSingle die (1 piece)\n\n\nManufactured by Chessex, a leader in gaming dice innovation\n\n\n⭐ Why Use a Countup&down™ Die?\n\nThis specialized d20 dramatically simplifies incremental tracking—no more scribbling on paper, tapping apps, or losing count during intense battles.
