I've decided to quit doing these since more often than not the NM Goblin brigade (that's what I call them when my kids are in earshot) are blocking the path.
For the leve for finding 3 mining spots to the NW of Tree speak: The last time I tried it the goblin gang was right on top of the mining point. I had to very carefully aggro them and lead them away first. This of course wastes a lot of time as I get killed and have to wait for my weakness to go away, plus run all the way back.
I had to do that 4 times during 1 leve to get to all 3 mining points. 2 of those times I just got killed too fast.
I have tried this leve 3 times since the NM Goblins were introduced and each time I've had to mess with them.
Once I tried to take the path just to the West to go around, but for some reason that path is outside of the leve area and I lost my leve that time....
For the other treespeak mining leve for High-Quality Obsidian that takes you to the far E area, I had the same issue again, where the Gobs teleported in while I was mining a point and then blocked my exit when the mining point moved to the tunnels before that open area. More time wasted dying, running back and getting unweakened.
It would be nice if you would considered having mobs not aggro DoH players during a leve or else change the locations of the spawn points for these mobs so that they don't conflict with Leves.
