1. I think that even with that boost of aura, Shalnark's strength wouldn't exceed Illumi's. Plus, Shalnark loses his wits when he goes on Autopilot. When I said he had to hide, I meant that he needs to click buttons on his phone to control his puppet, so he can't fight while manipulating someone.

2. He attacked the first guy he met, I think he would have slaughtered Kurapika and Leorio if he had met any of them after going crazy as a coot. Anyway, consider that Nen users never reveal their abilities, and most of them shun fame, so it must be hard for him to find decent opponents. I think he did not attack the Zodiacs because that would have set the whole association against him (though he might decide to do so in the future).

3. My guess it's he is no longer as powerful as Zeno or even Silva, maybe even weaker than Illumi. Don't know.
