I’m a bit confused about this, on the image it has the sign that either means increased critical chance or increased damage. In the description however it doesn’t say that, is this a typo?
It’s just a swap in fierce strike. So yeah, why does it have the Ferocity icon? It’s also possible that the swap prevention is applied to the user, since that’s what all SIAs do?
I don’t even think it’s a mistake in the notes, they might have just deliberately chosen this confusing icon because it’s “fierce” in the loosest sense - maybe someone confused “Fierce” and “Ferocious” somewhere down the line?
