Medizin der Wildnis (52) - Makes your
Tier heilen heal 15% more of your pet's health, which is a ~42% increase. This is a significant increase, which just means your pet can tank more enemies at once while leveling. This is not exactly a problem to begin with though, and will only be really noticeable if you are doing huge pulls while leveling.
Verbesserter einlullender Schuss (54) - You get 10 focus back from successfully dispelling.
Verbesserte Fallen (56) - Reduces the cooldown of your
Eiskältefalle and
Teerfalle by 5 seconds.
Verbesserter tödlicher Schuss (58) - Increases
Tödlicher Schuss's crit damage by 25%. This is a nice DPS upgrade, but just means Kill Shot will hit harder sometimes.
