Lowland Shore - Hunting in the wetlands achievement - where is the Velravn Knight?

[grimspectre.6981]

Is this achievement bugged, or is there really no such mob? A whole lot of us have been unable to find the "Velravn Knight" for the 2nd of 5 lines in the "Hunting In The Wetlands" achievement. This being the "There are reports of a velravn knight hiding near the upper waterfalls".

You need to do a pre quest before wit this bear infecting 4 places. After this the mop appear. But this event is such freaking overpowered with mops the npcs dies before able to spawn the boss.

What Miriam said,  last night I searched for over an hour only to get caught up in a quest following someone around, after that quest the knight spawns.

any idea the name of the NPC? i've done the kodan ardent gale one by the Valravn's Post POI multiple times now and never got credit for "Hunting in the Wetlands" 😕 Does the spawn have to be a champion to count? 

Update: Finally got credit for the event. Ardent gale appears in both the Exorheic Falls - Valravn's Perch POI (Wetlands ) , and the Lupine Fields - Valravn's Post POI (Grasslands) areas. both give credit for their respective "Hunting" achievements. So do both for anyone still searching.

When I tried this in the wetlands the enemies just kept spawning non-stop and the npc couldn't even get near where they wanted to go.
