They really need to take a page from Nioh when it comes to echoes.
For example, right now, the various elemental Prism echoes do this really weak and lame laser attack that does next to no damage. How about having an elemental Prism provide like a temporary 10 second elemental buff to your attacks?
So if you use an Spectro Prism, you temporarily get 10 seconds of Spectro damage on your attacks, even if you're not an Spectro character, sort of like how the Oni Bi soul cores in Nioh 2 (pic related) temporarily buffed your weapon with a specific element when you use them.
