That depends on your goals in RuneScape. If you want to train Dungeoneering, I suggest completing the tasks to receive the aura 4, which gives numerous benefits. Mainly, you get a second gatestone that helps traverse the dungeon more easily. Moreover, you start with cosmic and law runes in your inventory, perfect for teams so you can teleport to them quickly. Also, the Daemonheim achievement diary is a requirement for the completionist cape.
