How do you defeat lord Tanis?

[fluid patio]

I can't kill him. I am lvl 14 and have used those stems that boost your stats but it's still impossible.

[lost edge]

Do you have a companion enabled and did you set the companion to heal you?

[tough ledge]

Stims wont do anything at level 14

You need to make sure that:

. You got your companion activated

. You're the same level as the boss or overlevled for the fight

. You know his and your abilites and how to counter them
