It may be handy for you to change your graphical settings so that your lighting detail is set to low. Armour will only hinder you in this quest, so leave it behind to keep your weight down. Instead, wear weight-reducing gear like a Spottier cape and Boots of lightness, or Wicked robes. Wearing at least one teleport-capable item is worthwhile in order to allow teleportation to a bank to re-equip. An emergency teleport (one-click teleport) is not necessary as this is a safe quest.
