Has anyone completed them yet, and if so can you give pointers as to where to seek your targets? I'm currently building a damage-based Kubera's Staff for Stone V but can't seem to catch a break on Saplings in weather. I asked the weather checker NPC in whitegate but at most all she ever has is a chance of rain in the mire; I tried the Boyahda Tree for a while without any luck either. At the moment the best options I've come across are Merriphatad Mountains (S) and Caedarva Mire; but neither one has weather long enough to rank up significant kills and I want to make all 8 staves (excessive? Yeah, but it's a fun thing to work on and doing them in order of T-V release for SCH).
I think I'll go try Treants in Vunkerl Inlet (S) actually... everytime I'm there I see elementals up...
