This achievement is currently unobtainable.
There is a 15GB update today that makes this achievement obtainable 16.09.2020!:D
Requirements to get the achievement :
1.Hunt and kill the Packmaster
thus rewarding you the Tusk
2.Find the entrance to the Frieran Sea
in the same map *the entrance you are looking for will have a boat*
3.Peek on the side of the ship the armor to unlock new dialog with Sebum
4.Talk to Sebum and choose in the dialog the Tusk
for the armor below deck
Below a more detail guide on how to get the achievement:
1.Easiest way will be to start Adventure Mode
and on the Snow
area try and find the The Packmaster Yeti that we need to get the Tusk
If you do not find him in the first Snow area the easiest thing to do is reset the adventure mode on Reisum and start again. It took me 2-3 times to get him so varies as it is random but keep trying.
**Keep in mind that once you have the Tusk, do not reset the world again
or it will vanish from your inventory***This is purely RNG and is definitely a specific yeti in your world that drops it**.
2.Now having the Tusk in your inventory means the Frieran Sea
is on the same map, sometimes you might need to do a boss to get to the other side of the gate to find the entrance, but know it is 100% somewhere on the map.In all my plays where I found the Tusk I also found the Frieran Sea.
3.Now that you are at the Frieran Sea, before going up the boat's main ramp, look to the left and move along that side of the boat. You'll have to crouch and break some boxes to get through. You will find a place you can climb up and a hole in the side of the ship that you can interact with using
to see inside the hold. Inside will be the Warlord's
set and seeing it opens an additional dialogue with Sebum when you speak with him.
4.Talk with Sebum and choose the “What about that armor below deck?
”, then follow it up with “This Tusk, for that armor. [GIVE TUSK]
Sebum will then say that "you drive a hard bargain
" at which point the achievement should unlock. He'll then open the deck below and you're free to loot the armor set.
Have in mind if you select the option “I found the Packmaster here’s its tusk. [GIVE TUSK]”
Sebum will just give you some Scrap for it voiding the achievement and the armor set, so be careful with the dialog options else you will have to redo all again.
Goodluck and enjoy the new armor set!
