Primary
To procede through the Dragon's Lair mission you must talk to Glint at the end of a series of six distinct areas, so called "facets", one for each class. Each of these facets have their own distinct disadvantage. At the end of each you have to defeat a boss to open a portal to the next facet. Note that every facet boss has one Elite Skill that can be captured, so make sure to bring two Signets of Capture on this mission. The mission takes some time to do, but it is not very difficult and can be done easily with henchmen.

Bonus
After you meet Glint, do not go through the portal. Instead, pick up a dragon egg. Enraged, Glint will attack you. Kill her to complete the bonus. But, be warned, she is level 31 and very difficult. However, should you fail, do not worry; she will resurrect you and send you to Droknar's Forge anyway.

Helpful Tips

 * At the beginning of the battle, Glint will cast a hex, Crystal Breath, that causes exhaustion every time a skill is used. Anyone who can should bring a hex removal spell like Shatter Hex, Smite Hex, Remove Hex, Nature's Renewal or Hex Breaker (to prevent the hex from affecting you).  Because this is an AoE hex, your entire party will be affected by Crystal Breath.
 * Try to stand apart from each other if possible.
 * Use Blindness-inducing skills. For example, Rangers can bring Throw Dirt or Dust Trap, Elementalists can bring Blinding Flash.
 * Use Interrupt skills to stop Glint from casting her special "Crystal" spells.
 * Glint's attacks can be dodged by strafing, like arrows.
 * A good tanking Warrior can help your team immensely.
 * A protection Monk is useful for limiting Glint's high attack damage.
 * Everyone should bring a Resurrection Signet or spell.
 * When Glint is half health she casts Crystal Hibernation, which gives her +7 health regeneration and converts all non-physical damage dealt to her into healing (including weapons that do elemental damage). The trick here is to have casters stop using direct-damage spells (unless it is a health degeneration skill), and make sure all fighters switch to physical damage weapons. However, when the effect fades, beware of becoming hexed with Crystal Skin, which deals 100+ damage to attacks who deal physical damage - you should switch back to elemental damage at that point.

Egg Baiting
Another strategy for defeating Glint is to keep her from attacking, by distracting her with the eggs. Glint will only attack the egg-bearer if he/she is still carrying it. But if the egg is dropped, Glint will attack the entire party:
 * There are two eggs in the lair. Have two members of your team take turns holding an egg.
 * The two egg holders should position themselves far apart, so that Glint has to run back and forth between them.
 * When Glint gets near to you, drop your egg!
 * Everytime an egg is picked up or dropped, a message is broadcast to the group. If you are an egg holder, you should pick your egg up right after you see a message that the other egg holder has dropped his egg.
