The 2nd (right-most) Heartstopper shape is close to what is shown in Dreamcore video as Subterfuge Mask.

I think that the screenshot you send is the tree from a newer gamebuild. The one that is currently used in this project is missing some notables or they are in another location, including the Subterfurge Mask. In other words the tree isnt up to date. The tree from the game we are gonna play have round notables. While the current image has the old square style like POE1.
