I cant believe i never noticed this before.
This skill is litterally the only skill in the entire game that requires you to put an extra point in to it if you where to continue
You are forced to put a point in to Baneshing light otherwise you cant continue in the tree.
This means that going this route will always cost 2 skill points instead of the 1 that the others have. I dont know if this is done on purpose for ballancing reasons but after the Nerfs this skill had i feel it is quite on par with ballance on the other skill and the extra point is not nessesary.
I feel like Baneshing light should either be a seperate point that can be skipped OR should just become part of the inate skill. But forcing to put 2 skill points in the skill feels a bit stupid
