Medallion Trigger: Yes. Guardians are inherently magical beings; they are made of Light, so that ought to really set the medallion off even if all they're doing is standing around. Scent: Gun oil, sweat (not unpleasantly so), leather, metallic smoke, vanilla, coffee Pulse Detected (and description): Shaxx has the pulse of a supremely healthy, very athletic person. He generally doesn't lie, and if he tries it, he's so fucking bad at it that Geralt's not going to need his pulse to tell. Gait/Breathing: Not a stealthy man. He actually is very light and quick for someone of his size. But he also purposefully makes noise when he's walking up behind people most of the time. Axii: Not going to work. While it possible for Guardians to be controlled, it's only been accomplished by beings way more powerful than Geralt. Sorry, buddy.
