Immune, WTH?

[GIJoeWWW]

I'm in HELL ACT I, trying to get the relic so I an go to the drowned temple. The ancient warrior or whatever is completely immune to anything I do, my caltrops hardly slow them down at all. So wth am I supposed to do, just give up? Thanks for any tips.

Feel like I'm in the movie Independence Day, the aliens all have energy shields. That is just cheating.

Is he shielded? If so wait until the shield is down for a moment and start hitting/shooting.

If he just keeps shrugging off your hits, get a better weapon.

Later you will face sometimes uniques that have invulnerable minions. Then you ignore the minions and keep hitting the unique, minions die when the unique dies.
