I got a single point into the Shadow Stalker from the Occult tree and was pretty disappointed. He didn't do much damage and he died very quickly. Being as that I really wanted to make a Dream/Occult summoner, I stuck with it and I am now glad I did. I have a few points into Shadow Stalker and Channel and he is starting to be a force. While he still can die pretty quickly, I can see him getting more and more powerful.
When leveling Channel, he got the Shadow Rush skill, which only gives a vague description of what it does. This ability is giving me +2 skills (which I use to resummon a more powerful version of him) and who knows what else.
Is there anywhere that has what each skill exactly does? I'm sort of a numbers kind of guy.
