Time to do another character. This time, I'm going to split the guide over a few posts, instead of having one long unwieldy post. As always, please feel free to post suggestions, and I'll add them to the guide.
General Notes
Harsk is the ranger of the party, and wins all of the team player awards. He tends not to shower himself in glory, and likes being left alone for the most part. His most important ability is to snipe in on other character's combats, and will often end up dumping almost his whole hand to do so. His personal explore rate tends to be somewhat low, because he's already used most of his hand helping everybody else. You'll probably find that by the time it gets to his turn, his hand will be empty. And that's perfectly OK. When only one location is unclosed and you have the time, you'll often plonk him down in a closed location, just so he can help somebody else out against the villain.
Because Harsk can only help when he's at a different location to the combat in question, he'll tend to be alone on the map. To make the most of his contributions to the party, make sure that he actually has a party: give him at least a couple of other characters for company. As he can't help himself with his best power, he tends not to do so well going it alone.
