You are always allowed to buy things from shops if you can afford it. Check the RS wiki for shops that stock items you need for your task. If none does, you can kill monsters or create it yourself. When killing monsters, you cannot kill any that drop items which complete tasks. There is an exception. Look at rule 2.E2. Monsters that drop items which can complete tasks, can be killed, if the drop is equal to or rarer than 1/2000. Champion's scroll, for example drop at a 1/5000 rate, and therefore giants, ghouls, and others are decent training methods. On the next task we'll talk about creating items!
