This is by far one of the easiest.
Now there are several popular methods and spots that you can work with to level up your werewolf skill line.
However, I recently created a new Stamina Based Sorcerer and got the werewolf curse for a role-play character I’m building.
I decided to try and find the easiest way to level up my skill line that didn’t require running all over the map. Now there are plenty of zones that have areas that are heavily infested with enemies.
The best go-to I have found was Bankorai.
Just outside of Evermore, there is a small village that has an abundance of undead and other enemy NPCs.
I started at Level 1 and worked my way up. In less than an hour I maxed out my werewolf skill line. Simply by running through this village killing mobs, feeding, and moving on.
By the time you cleared half the village most of the earlier kills have been respawned, so losing your werewolf form isn’t even a possibility.
Some additional tips. Ensure your backpack is empty or buy a few bag spaces because you will be picking up random Loot if you decide to pick up any.
Treasure maps also drop alongside some other treasure items and even companion gear if you have one equipped.
If you do lose your werewolf form for some reason. Visit a friend’s guild Hall and use an Aetherial Well to instantly fill up your ultimate again.
There are two-way shrines very close to this location, making it very easy to get to.
