Scent Tracker

Pick one opponent's scent out of the air and follow it. Their trail hangs behind them as a thread of drifting scent, thickening and brightening the closer it gets to where they are now - and while you hold the scent you can pick them out through walls.

Tracking something also puts you on edge: your claws find the gaps more often while the scent is fresh. The moment you mark them, they are briefly easier to hurt.
