I explored Hoth before coming here. I found a mountain top hoping to find the dangerous wampa, as described in the patch notes. I found two young wampa. I killed them and their mamma came. I killed her, she dropped nothing. I also found a chest there, inside was a purple enhancement.

I stayed there a while. The young wampa spawned again after 15 minutes. I threw a grenade at them and it TKO 1 shot both of them.. the mamma didn't spawn. I waited 15 more minutes. The young wampa re-spawned. This time I just walked up to them slowly, the mamma came. I killed them, no loot.. rinse and repeat for 3 more hours. The chest spawned every 40 minutes or so, inside the last chest I looted tonight I found:
"Ice Scrabbler Liver" x1
DEVON-WHITE on Ajunta Pall.
