please report any bugs
First off let me say that i have so far only tested the throwing knives so i cant speak of all the new throwing weapons.
I started a new Ranger and equipped her with dual wielding throwing knives and i noticed they are labelled as swords which means the game treats them as melee weapons. That means that all the skills that require 1 sword + 1 melee weapon are usable with dual wielding throwing knives. The fix should be fairly simple such as renaming the unit-type or whatever it's called in GUTS ( im no modder so i havent got a clue).
Good news for a berserker though, now they got ranged weapons that can use the blood hunger passive skill hehe..
