Greetings,

I have problems with this part of the quest Source of Power from Dreveon at Dalimond (part of the Tier II revamp).
Here is what I'm asked for this quest:


The directions are not very precise. I made several turns around the Observatory blighted area, climbed to the top of the Observatory mountain 3 times, killed and looted many monsters of any type I could find... and so far, I was only able to have my counter at 2/10.

The problem is I have absolutely no idea of what I did to increment it! I got no feedback from the game, I don't know if I have to go to some specific places, kill some specific mobs or loot some quest items. For the loots, I haven't noticed to have got anything special... the usual crystals, hoard items, blight equipment pieces and junk loots.

My question is: what am I supposed to do?

Thanks in advance.
