Hello, Gwydion!
Thanks for your inquiry!
We wanted to confirm some information concerning Treasure Hunter, in general:
• The maximum value you can achieve is 8. This can be obtained through equipment, job traits, and Atma.
• If Treasure Hunter activates while attacking, it adds +1 each time, up to a value of 12.
• With the above factors considered and combining them with the Job Gift that increases Treasure Hunter's effectiveness, you can achieve up to +14.
With these in mind, there should not be any Treasure Hunter differences regarding notorious monsters or monsters in general found within Dynamis – Divergence.
