If I'm grinding law runes in 'Old School RuneScape' and want raw speed without fuss, I lean hard on the Abyss method. It’s straightforward: bring as many pure essence as you can carry in your inventory and in your runecrafting pouches, pop into the Abyss from Edgeville (Amulet of glory or teleport to Edgeville makes this quick), slip through to the Law Altar, craft, and hop back to the bank. The magic is in the pouches — small, medium, large and giant — because they let you minimize bank trips and maximize runes per hour. I always wear a law tiara if I want to save inventory space over carrying a talisman, and I use the best teleports I have so the loop is as tight as possible.
Gear and QoL choices matter: bring a weight-reducing setup if you care about run speed, and use stamina potions if you’re running long loops outside the Abyss. Protect your valuables if you ever run near dangerous spots, and consider using the Abyss because it bypasses talisman requirements and keeps the cycle quick. For me this combination — pouches, tiara, quick teleports — produces the fastest pure law rune throughput, even if it’s less XP-efficient compared to some alternatives. Give yourself a playlist and a timer and you’ll see steady gains; I love the rhythm of those tight trips and the satisfying click of crafting stacks of law runes.
