as a lvl 24 bst these mobs con DC-T, best guess is they are 23-26. they are plentiful and surrounded by lots of other EP-EM mobs, making this look like really good bst grounds for 24ish. unfortunately, they have exhibited a huge resistance to Charm. no other mobs have given me such a problem trying to Charm as consistently as these. as i write this i am laying dead by the dock after failing to Charm a DC 5 times, and this is not the first time this has happened.
Drops Flytrap Leaf worth 1300-1400 (1384 for me in sando, depends on fame) at npc, and 1000 at AH... very rare drop 40 kills for 1
Maybe you just had bad luck, but when I went there exploring, I killed about 20 and got about 5 drops. It's under alchemy in AH. Not sure what recipe they are used in.
Went in with my BST and tried to actually charm one. I only got off one charm before I got link aggro'd and died. But the trap did con even to me at 27 and there were some decents around also.
When I was in Carpenter's Landing, I found about 3 or 4 flytrap leaves. I had no clue what they were for and I wanted space for tiger stuff, so I dropped all but one. I'll keep them next time!
