I had a 90 hour playthrough as a ranger. It sucked. Yes, its broken. Works on object though haha. When it did work, it worked when they were full hp - guessing that damage gets applied first so then the "check" to see if they are full hp is no, so it adds it. for the most part, i very much regretted my 1 shot per turn with nothing really else to do guy. Underdark? Had darkvision, still took huge penalties from enemies being in shadow. Hunters mark? Theyre too far away, but in range of your bow. You cant hunters mark something you can shoot and they both have a range of 60ft. fuuuuuuuuu
Yeah i think the "check" is done after the 1st hit lol ! So you apply anytime this passiv ^^ Easy to fix, isn't it?
But the hunter's mark is too buggy atm imo.
