Potato cactus

Potato cactus is a members-only item that currently has the following uses with two member skills:
 * Herblore – as a secondary ingredient when creating magic potions.
 * Summoning – as a binding component when infusing spirit kalphite pouches.
 * Gathering potato cacti is a good way to make money if one is a low levelled player. Due to the amount of bots doing this, however, it can be very hard to sell on the Grand Exchange.

Kalphite Hive


There are a total of 14 spawns in the Kalphite Hive:
 * 1st level – 3 spawn in the south-west room where the Kalphite Soldiers are found.
 * 2nd level – 7 spawn on the west wall next to the lethal Kalphite Queen.
 * 3rd level – 4 spawn, one in each of the corners of the room. This part of the Kalphite Hive is accessible only after the Do No Evil quest by climbing down a hole in the 2nd level next to the Kalphite Queen, or by taking a hidden entrance south of the desert entrance.

Note: Prior to a player entering the Kalphite Hive, it is highly recommended they bring along a few antipoison potions or alternatively, an Anti-Poison Totem, as Kalphite Soldiers and Kalphite Guardians are poisonous. Kalphite workers and the Kalphite Queen, however, are not poisonous - but be warned that the Kalphite Queen is level 333.
