Tips and Strategies

Killing the Behemoths

You can take out the Behemoths' components using Tearblast Arrows to have a smoother time fighting them. It will also take a large portion of their health if you remove multiple parts at once.

One way to kill the Behemoths is to override one and let it fight the hostile one. You can only override a Behemoth after finishing the XI Cauldron.

Aim for the Head and Perform Stealth Kills

Most of the enemies you'll encounter on this quest are humans. Conserve arrows by aiming for headshots and performing stealth kills. Elite enemies might take a couple more hits unless you have the Leader Strike skill active.

Beware of Proximity Traps

Be careful when following Rasgrund. He has placed Proximity Mines all over the place, that will explode after a short while once you get in range. You can trigger them using Fire Arrows or activate them with your body and then get some distance to avoid taking damage.
