I have ran into these... and they quite dangerous enuf to make a full alliance (18/18) wipe. Also the drop rate is extremely low as i have never seen an Attestation for any relic weapon drop yet and i think our LS has killed 30 of this type of mob in Dynamis - Beaucedine.
Quadav section: On your way to Fei'yin after u walk north along the cliff area the area down the ramp is the quadav section.
Orc section: The area down the ramp from the Quadav section is all Orcs.
Yagudo Section: The area up the ramp from quadav.
Goblin Section: in the Yagudo section there will be a ramp heading up towards Xarcabard, thats all goblin x.x
Mixed Section: The very first area, and final area before the lake in the north by Angra Mainyu is mixed.
Hydra Section: In the Goblin section theres one last ramp to Xarcabard you will see eyes and more eyes x.x when u aggro them they will spawn one or two hydra mobs, they are NOT NMs. by the "Nue" tower theres a trigger Eye which will spawn the Attestation NMs which are located @ the towers scattered all over Beaucedine.
