What does this information mean?
- Return and speak to Nagafen in The Arbiter's Master instance of his lair. I can now enter Deathtoll and plunder its treasures.
- Inside Deathtoll, in the Dragon's skull you will come upon a Barrier that cannot be breached, go back to Nagafen. He will give you a scale and tell you to meet the armorer in Solusek's Eye (Keortor Talyse, same NPC as relic armorsmith. -68.56, -626.30, -58.67). He will make a symbol that will allow you to breach the barrier.
[edit] Rewards
It is possible to 'solo' to the flameshield in a 'suicide run'. Get see invis and see stealth of some sort (the tinkered goggles work nicely) and zone in and out of DT until you get a good instance -- one where the eyes are out of the way of the run from the left side to the skull. Then sprint to the skull, die, but get your update. Totem of the Owl and Totem of the Butterfly also gives the ability to see invis and see stealth.
