What is this node called

I cannot find it, I can only find the set node that can edit the values of variables, I got the screenshot from a tutorial.

To use that version of the Set node, you’ll need to drag a wire off of another variable that contains the target object that you’re trying to change the ‘Target Blueprint’ variable on. (That’s the one that’s wired into the ‘Target’ pin)
