skills were also not bad
+5 on proficient skill, +3 for skill focus(now...
I would replace HM with a something that is not a spell.
As a Bonus action or when you hit a target with an attack you can "mark" it.
Once per turn you deal extra damage equal to your proficiency bonus.
You have advantage on Insight, Perception and Survival checks.
Mark lasts until you finish a...
