...and if stealth mode is made a part of it, I suggest that each race gets unique methods.

Elezen get leafy camouflage.

Roegadyn get a little tree branch that they hold up in front of their face and crouch and somehow this works.

Lalafell get a larger person (such as a retainer, a nearby NPC, or their intended target) that they're clinging to the back of.

Hyur get a barrel.

Miqo'te get a cardboard box.
