At average speed, one can do about 60 trips to the law altar via the Abyss per hour, using the amulet of glory to teleport back to Edgeville, and using the tool belt items to mine through the rocks in the abyss. You need to recharge your pouches every 7 to 9 trips, to prevent the giant pouch from degrading.
The Mage of Zamorak is located low-level wilderness, near the source of the River Lum. You cannot take any armour nor weapons to law altar, because law altar is located on Entrana, the holy Saradomin island. Therefore you have to be cautious about PKers and while you are in the Abyss. See Abyss#Strategy for more information on how to navigate the abyss. Once inside, enter the law rift and craft the essence in your inventory and your pouches. Teleport back to Edgeville with an amulet of glory and repeat.
The amount of law runes crafted increases at higher levels, up to about 45% at 99, due to the greater likelihood of crafting two runes per essence. This results in a increase of up to 1,458 law runes created per hour, equivalent to an extra 457,812 in profit.
