I’ve purchased

The Lumarian Brazier ( very happy with this , its huge)
The Jebal Sag Statue
All the wall paints
The Thrall pot ( which i regret cause thrall pots are still broken so its useless)
The Werehyena (he doesnt hit hard and his AI is sluggish, but man he has a ton of HP)

for grinding i just pick one of the bosses, in my case the Panther and just spamed him. Champion respawns every 5 minutes, so i would just sit there and kill him over and over.when Im out of lures, take all the fangs and spend them all on lures, rinse and repeat. eventually you’ll have like 50 + lures and after killing him 50+ times in one grind session you’ll have like 800+ fangs, head back and buy a bunch of stuff from the vender. Save like 50 fangs, buy 5 lures, start again.
