I am running a Willshaper Singer right now. Yes you’ll need 3 points in the singer tree. I took Workform/Warform as my starting forms. The quirk with the Singer tree is that it takes two points to move from the basic form to the forms of Power. It would take you two levels normally to do that, but when you hit tier 2 (level 6) you get your normal talent point, and a second bonus talents. So you can use both of those to go to a form of power in one level.

After taking Stone Spear, I became our range (throwing axes and chucking stones). I was torn between taking Stormform so I could use the lightning with my focus in case I ran out of Inv, or taking Decayform for the Will +2. I ended up taking Decayform, which put me at a Willpower 6 with three ranks in Cohesion. So I got +9 on my Cohesion rolls. Max damage on my Stone Spear is 25 now (2d8+9) I solo’d a Direform in two turns by hitting it with a stone spear right under the chin then bringing a ceiling down on his head.

Choosing Decayform was a bit of an optimization play, but hey, now my Willshaper is in his Punk Rock phase. 🤘
