Minigames are timed grinds for specific unique rewards — for example running Viking Assault until you earn a piece of the Fighter set. Each minigame task shows its expected duration and its reward. Minigame uniques are granted server-side when the grind completes and count toward your collection log. The Fletching Guild (Ardounne) is a 2-hour grind for the Bowyer's Knife — an untradeable tool that cuts one tick off the time to fletch any bow while it's in your inventory or equipped. Autumntodt (Catherra, unlocked at Firemaking 80) is a 5-hour grind for the Tomb of Fire. Lithe Farm (Seerhold) needs both Farming 50 and Herblore 50 to enter, and every task inside it is gated on the pair; its 2-hour grind earns the Magic Secateurs.
