Engwithan waystation level 2: I have killed the first group of imps without problems.

Then I continued to the next room. There were 2 imps. I attacked them and got exp for killing both.

The second imp got killed by crippling strike of my rogue/soul blade, but it continued to attack me.

I cannot target the imp and so I am stuck in combat.

 

PS:

What do the cog wheels at the character portraits mean?

When starting the game, in the main menu there are also movings cogs over the continue and load button for a second.

I reloaded the game and this time I could beat the 2 imps without problem.
