1. Ultra Rapid Fire
How can anyone forget about Ultra Rapid Fire!? Ultra Rapid Fire, mainly referred to as “Urf,” has been one of Riot’s most popular limited time game modes they have ever released. The “Ultra Rapid Fire” game mode allows champions to have an automatic 80% cooldown reduction, no mana or energy costs, bonus gold income, attack speed, tenacity, and critical strike. This game mode was built for the pure enjoyment of the players. Ever since this mode was first released players have been begging for it to come back year, after year, after year.
