how do you charm juvenile smokescales in tangled depths.

i have been to the 2 locations where they spawn but i am unable to charm any of them,this happens every time i try to no avail.any help would be very welcome.

Hello fellow Ranger :)

From gw2 wiki

Teku Nuhoch — Outside the camp and to the south, between the two cave entrances leading south and east. The Juvenile Smokescale will only spawn if Teku Nuhoch has reached max strength (all meta events at outpost complete). The meta event will say "Success! The Nuhoch have raised fierce battle beetles to help defend them." when the camp has reached max strength

SCAR Bivouac — South-east of the SCAR Camp Waypoint. North-west of Vine Wall point of interest. A Juvenile Smokescale will only spawn after SCAR Field Operations reach max strength. The meta event will say "Success! The Mordrem migration has been halted, and the SCAR team is maintaining their position."

i know about the meta but each time i go to the spawn sites the juveniles are there but they won.t charm.do you have to actually have to do the meta events so that they will charm for me.both events are saying success but i still can.t charm any of them.

Do you already have them as a pet?Are you doing this on a character who is a ranger?
