Avatar Leech Trials

So I am stuck on 2 of my smn staff trials, the ones for Shiva and Ramuh with leech kills. Bostaunieux Oubliette is where wiki says is best and does seem to have a decent lvl leech. But the leeches are now overrun with ppl lvling off them. I then tried Aydeewa Subterrane since there is supposedly 56 leech spawns. I have found 1 room with 2 and 1 room with 6 and no trace of the other 48. I then went to aby. But with ppl farming fistule and getting bloodguzzler pops the lvls jump up on the mobs and there are few to be found even with the fast respawn rate thanks to fell cleavers.

Am I missing a place that would be good to do these trials, I need Ramuh and Shiva specific kills and just am having a problem finding a good camp. Any suggestions? Thanks!

Caedarva Mire. There's only 14 spawns, but they're slightly easier kills than the ones in Bostaunieux and they don't aggro.

Alternatively, Toraimarai Canal has Bouncing Balls, but there's only 10 of them.

the Fistule area prolly best, just go during a slow time, and if you see ppl killing for pops, offer to kill for them and give them the pops so they dont mess up the mob lvls

You might try some of the deeper areas of the Boyahda Tree. I seem to recall few leeches in that area with the Ancient Goobbue NM. They're about level 75 and ou can fish some up around there too for roughly the same level.

Cant you drop in to the peeps levelling on level sync?

Yeah that works too.
