The Call of the Hunt is a trait that allows a warden to invest XP into what they are fighting to gain knowledge on how to fight it such as weaknesses, capabilities, vital signs, etc. The warden can use the xp they would gain by defeating it to invest with, but must slay the enemy to make it permanent.

Effects
The following examples are what can be learned from an enemy.
Weakness: when using this triat, investing 100XP in an enemy while fighting it allows for a warden to learn how to isolate weak points, anathema such as elemental weaknesses of creatures with the same tag, and the creatures strengths.
Tracking: a warden can learn behaviors, preferred diet, natural predators, and other traits of an enemy by studying it while tracking. This costs 30 XP, and can be done at any point so long as the creature has been in the vicinity within a day. They can also learn other elements such as if and how they can be tamed and trained, influenced, or repelled. this would require at least 50 XP invested overall to learn.
