Following a number of rumors and an eventual leak, Lego has revealed its first collaboration with Dungeons & Dragons: a new set inspired by the classic tabletop game, just in time for its 50th anniversary. Officially titled the Lego Ideas Dungeons & Dragons: Red Dragon’s Tale, Lego Insiders can pre-order the $359.99 set starting April 1 exclusively from the Lego Store, while everyone else can roll for initiative beginning April 4. Pre-orders placed before April 7 will also receive a complementary Lego Dungeons & Dragons Mimic Dice Box.
