Preface

Hunting provides great benefits for its user, regardless of what they hunt. The mastery greatly improves skills related to hunting, allowing the user to stalk their prey, set up traps, figuring out the prey's weakness and exploit it, as well as improving their investigation tool, allowing them to get more information out of their environment.

With its diverse skill set, hunting is most optimal in the wilds rather than cities. It skills make the user very efficient at chasing targets they set their eyes on.

Mechanics

Trapping	Detecting, assembling, disarming, setting up, and crafting traps.
Stalking	The hunter can track their target very effectively without fear of being seen. It is not full stealth like Incognito, however.
Exploit Weakness	Hunters learn about the weakness of creatures they encounter often. This leads to having the knowledge of how to exploit an enemy's weakness, which is recorded in the UI. This allow the user to do more damage to these enemies.
Inquisitive Eyes	This mechanic improves the Hunter's investigation mode, and add in the ability to track foot prints. It also enhances the Hunter's ability to listen in on conversation and record information more effectively than those without the mastery. This also allow the hunter to assess their surrounding better and spotting enemies before they are spotted, often leading to improved initiation for themselves and their party.
