Location Experience gained


The Sinister chest, located in the Yanille Agility dungeon, always rewards nine herbs when opened: three grimy ranarr weed, two grimy harralander, and one each of grimy torstol, grimy irit leaf, grimy avantoe and grimy kwuarm. Opening the chest requires a Sinister key, and the key is used up when the chest is opened. Depending on the price difference between the keys and the herbs, it can be very profitable to buy sinister keys, open the chest, and sell the resulting herbs. The price of sinister keys jumps around a lot, but it's not uncommon to buy them instantly for far below the market price.
Start out by teleporting to the Watchtower, go down the ladder, and run east to the dungeon entrance. Slash the web, go down the stairs, and across the Agility ledge. Enter the obstacle pipe immediately next to you and open the chest at the end of the room. You will be poisoned. Open the chest 2-3 times (it takes about 8 seconds each). Depending on the price of the grimy harralander, it may be worthwhile to drop them so you can use more keys per load. When you've used all of your keys, teleport out using your choice of teleportation jewellery, bank the herbs and repeat. Each trip takes approximately two minutes.
