Zone: Blazeridge Steppes (40 - 50)
Closest Waypoint: Lowland Burns Waypoint (Nothern end of zone)
This is the lowest level and one of the easiest dragons there is. The dragon is mostly a straight forward fight once he lands, just deal damage to him and at about 50% he will summon an army of adds for you to kill. Take out all of his adds and continue to focus on the dragon. He'll be down in no time and you'll get your chest of loot!
Oddly enough the prequest can be harder than this dragon depending on how many people you have waiting to do it. For the prequest you'll need to port to the waypoint just to the south of Lowland Burns Waypoint, the Guardian Stone Waypoint. From here you will want to head just to the northeast to the Shattered Palisades. Here you will need to collect Siege Weapons for Crusader Blackhorn which will be used in the fight against The Shatterer when he lands. Hence, pre event! (or quest if you prefer that).
Now the reason this could be harder than the actual dragon event is because depending on how many people you have you'll have to collect more and more Siege Weapons which drop from the Ascalaon Ghosts. This could take ages especially since the ghost's camp is so small. However once you get that done you can just run right on up to the dragon and take him out!
