Soloed the level 75 version. Bind and Gravity were easy to stick - no resists despite 7-8 gravities with no staff or an earth staff. Does not link with surrounding Karakul. That means if you're careful, you can just Poison II/kite it to death without getting hit. I went melee part of the time, and it seems to pop 2 Chigoes every 100% TP.
I meleed because it has a lot of HP - 10k at least. It has normal evasion but hits a bit hard - 80-100 with cocoon or earth staff (but not both), plus phalanx/jelly/cheviot cape. I switched to Earth Staff and bound it when Chigoes popped out. Phalanx + Blaze Spikes kills them in ~2min without causing you to lose claim.
Wish I had brought a dagger instead, as well as a shield. Then I could melee almost full time and clear the chigoes with cyclone. Or as RDM/BLU it's practical to keep stoneskin up back-to-back and use ceremonial dagger.
