The patchnotes as of March 06, 2026 state that Silver's Tail Whack is no longer considered a movement ability. Testing on March 08, 2026 indicated that her Tail Whack is still being disabled by effects that apply immobilized, such as Paige's Captivating Read or Warden's Binding Word, but not effects that specifically disable movement abilities like Slowing Hex. Edit: None of her other abilities are disabled during Immobilize, just her 2 (which is without a doubt intended to be disabled) and Tail Whack (which isn't a movement ability per patchnotes but is still disabled on Immobilization.) Because of this, I made the post.
