The Dance of Shadows looks to be everything I was hoping for a Shadowseer to have. It seems the Harlequins are getting some of their own powers in a discipline called Phantasmancy. I have always been a fan of the Shadowseer model, and have a couple of them painted up. Most likely I will have to get a new one as well.

The Harlequin Discipline is called Phantasmancy.
Power #1 is called Dance of Shadows and its rule is as follows:
"Dance of Shadows is a blessing that targets a single friendly unit within 18". Whilst the power is in effect, all models in the target unit have the Stealth and Shrouded special rules."
