How To Slay Your Dragon

Best daily quest ever! Must be honored with Sons of Hodir and have completed Raising Hodir's Spear

Take the Spear and find a wild wyrm flying around west of Dun Niffelem and throw the spear.

You will find yourself flying around on a wild wyrm gripping onto its belly and you gain a new action bar as if you were in a vehicle, there are 4 abilities for phase 1 (theres a total of 2 phases).

Grab On - Tighten your grip increasing the number on the grip buff by 10.

Dodge Claws - Moves you closer to the wyrm allowing you to dodge its only attack for the next 2 seconds. 4 second cooldown (does NOT have a global cooldown)

Thrust Spear - Jab Hodir's Spear at the wyrm dealing 1000 to 1300 damage. Decreases grip by 5

Mighty Spear Thrust - Thrust Hodir's Spear deep into the wyrm dealing 9k to 11k damage but you cannot take any action for the next 5 seconds while you pull the spear out (this includes dodging). 10 second cooldown Decreases grip by 15

So basically you cannot let your grip fail and it decays over time, slowly at first but will eventually become too much to handle. (I think its about 1-3 min don't know exactly before it becomes too much to handle). If the buff fades you will fall to your death.

Constantly be using Thrust Spear on the wyrm while keeping your grip above 35-40. When a warning pops up alerting you to its claw attack use the Dodge Claw ability and after it use Mighty Spear Thrust. The objective is to get the wyrm to 25% of its health to force it into phase 2. If you think your grip is decaying too fast use Mighty Spear Thrust and hope for the best. At 25% you go into phase 2.

In phase 2 you are in its mouth (O.O) you have 2 abilities.

Pry Jaws Open - Prys the wyrm's jaws open by 5 degrees increasing your chance to hit with fatal strike by 5% per application. (stacks 20 times)

Fatal Strike - Throws Hodir's Spear into the wyrm's throat instantly killing it has a 0% hit chance on its own you NEED to use Pry Jaws Open.

So now youre flying around in its mouth. You gain a debuff called Jaws of Death which hit me (premade hunter with all that blue premade gear) for about 632 a second. The damage is physical so it might be affected by armor not sure though.

All you need to do for this phase is pray you didn't get hit by too many claws in phase 1 and use Pry Jaws Open as much as you can before attempting fatal strike (10+ stacks is nice but I live on the edge and go to 20 with almost no health left its intense!) If you are close to death and not at 20 pray your fatal strike hits.

Once he dies you fall to the ground (still in its mouth very cool) hit the ground and jump out.

Congrats you just killed a giant wyrm with only a spear. ^.^

The connection to nordic mythos is disturbing for those that know it. Hodir is most probably a reference to Höður hinn blindi (Hod the blind). Loki tricked Hod into thrusting a spear with a mistletoe tip at Baldur (Baldr the beautiful). Baldr's mother, Frigg, the consort of Óðinn the highgod of Valhalla had asked every plant in nature to spare Baldr except the mistletoe, thinking the plant was too weak to hurt anything. This resulted in the gods taking great pleasure in tossing things at Baldr, amused that nothing hurt him. Well, Hod could not see what it was he tossed so Baldr dies, Loki gets chased around the world for causing his death and incarceration in Hel, eventually caught and trapped at the roots of the earth in an exceptionally lurid BDSM position (chained to the roots of the earth with a snake hanging over his eyes dripping venom, Loki's wife standing at his headrest with a bowl to catch the snake's venom, once in a while the bowl fills and she has to empty it out, venom drips in Loki's eyes and he shakes the roots of the earth causing earthquakes) starting the plot for how to get even with the gods of Valhalla. Eventually Loki leads the Naglfar (ship of nails, as in, human nails) from Hel in Rangarök (literally: end of Gods).

In short: kill beauty and start the sequence that ends the world.
