For a party of people around level 60, try and tank this sucker from a distance. Use an Earth staff if you have it too, Wyvernpoacher's melee attacks are much more frequent and painful.
Otherwise, get this for your favorite RNG. This is the X-bow of X-bows in this game. When your RNG needs to hit, this is about as good as it gets.
We were lvling in Gustav when it came walking by. We had a pt of 58-60, got our plan down and killed it. We were down to the last few mp and all 2hr used up. I'm not sure if the xbow is any good.
although i can't imagine this thing diong as much damage. but still it would be incredibly usefull, and i'd like to get one for my RNG when the time comes.
Keep in mind that at level 52 you can use Darksteel Bolts as your primary ammunition, which do 50 damage on their own. Also keep in mind that you can shoot this type of crossbow about twice as often as some of the longbows.
And the fact that you can shoot an Acid Bolt to weaken the mobs defense... THEN use Darksteel bolts and you'll end up doing more damage than Eurytos bow.
yeah i have this bow by killing the goblin in gustab tunnel as well. dont remember the name either but the goblin almost killed are alliance of 58-60 had 12 people but it droped like 5 bombs =P
