Enter the town of Vretchpool and in the potions shop you must speak to an NPC named Tildias. He will ask you to head north of the town between the shore and the mountains and kill 100 ettins. Once completed go back and speak with him and you will be rewarded with 75,000 epool and an ettin snout ring. It protects 15, resists 5 arrow, 7 soul, and 10 disease, and adds 4 to dex and strength. In spite opf beeing an easy quest for any player than can solo Ettins, it can take a long time as spawn is very rare. A good option is to do it during a sp+awn increase. You must be sure you hunt inside the right area or kills will not count. This quest can be repeated.
