Like the rest of the zones, I took the strategy of getting all 3 partisan and all 3 merc tasks before working on any of them. When you zone in, there is a quest giver, right there. One partisan task acquired. Check. You then notice phase spiders walking around. Cast regular invis, and they are no longer aggro. Simple. Following the path, everything seems fine, until some skeletal excavators (undead) aggro from far way and start to chase you. Time to burn your fade to lose aggro, recast reg invis away from them. Along the way you find quest givers for partisan 2 and 3 quests. You then reach the castle, that splits the zone into 2. Mercenary quest giver is on the other side. Looking inside the castle you see a large number of undead restless paebala. They don't see through ivu. So you run through the undead rats, and the next thing you know you have aggro'd the chetari. They look the same as the paebala, however they see through everything (even SOS I hear). Other than clearing them, the only way I was able to get past was to mez all of them (which in sets of 3 isn't easy). Mezz/blur them, lead group past. It should be noted that there is a way to levitate over the castle, but it isn't easy - good luck getting a group across. Anyway, mission accomplished, all 6 quests acquired. Time to work on them. I won't cover all of the tasks in depth, but they did have some trends. They forced the group to repeatedly cross through the castle with its pitfalls. But then the quests get mean. They send you into the caves of DN. The caves are populated mainly by 3 types of enemies: undead paebala, see everything chetari, and swarms of beetles. The beetles con light blue at 115 and come in groups of 10-20. They cannot be mezzed. They are a challenge for a tank, and easily dispatch non-tanks. They don't see through regular invis. The temptation is to cast reg invis and run by them, but then more often than not you encounter an undead paebala who breaks your invis, and now your group is facing the swarm and undead at same time which usually means instant wipe. Double invis does help, but with the chetari around, that isn't a guarantee either. So the safer strategy is to clear the creatures. And that is a painstaking task. As you spend more time delving further and further into the caves, you have a thought in the back of your head. We have been in these caves over an hour. If we wipe, we would have no choice but to start again from the beginning... So you start to become more risk adverse, trying to make sure you always have one person that is FD at a sign of trouble and hoping they can rez the group. Eventually, you reach your goal, gate out of there in one way or another, return to quest giver. And the quest giver sends you even DEEPER into the caves. Many of the quests are not tasks that you will complete in one day. So the next day you hope to find another group going deep into the caves so you can get the next task update. The quests are brutal, and yet, having completed them, there was a deep satisfaction at the completion. There was something special about a dungeon crawl where the mobs respawn, and you can't just instantly run back to where you died. Where death truly had meaning. While overall, I am not impressed with the COV expansion, this zone is truly special.
