Entangling Roots Frenzying Thorns do not appear to be applied to Upheaval Totems for the Attach Speed buff.
Here I have stripped my character of all attack speed idols, and passive points. It’s easiest to tell by counting the number of strikes and sound effects, but you can also see that visually there is no noticeable improvement. At 50% attack speed, there should be a detectable difference between the two but it does not appear to be the case.
Like with all testing of totems, it’s hard to do in controlled environments so I might be missing the actual attack speed increase but it certainly feels like it’s not applying.
