This really made me mad. I approach him in the cave with the control device and manual. I saw him, before the battle started i inputted the commands for him to self destruct, didnt work, to disarm, didnt appear to work either. Started the battle, was doing damage to him, got him down to about 1/3 health, tried the disarm command and.....he restores all his health? self destruct didnt work either. Also when its my turn and I hit him with a bow, he randomly restores health? Is this intended?

Did arhu troll with that manual? None of the commands work, all restore his health.
