I've posted this in feedback and no response was received. guess i'll put it here bowmen have missing issue on snowman due to mortal blow, dropping arrow does not help, still activates mortal blow and causes missing
As the fix for this issue would require a patch, we will likely not be implementing a fix at this point of the event, but will try to make sure it's sorted out for next time. Thank you for the report.
You can avoid the misses. Just melee the boss. Or hit from a long distance with the snowballs, because it will activate your mortal blow as well. I am a MM and I know how hard it is.
I tried everything, it just activates. Especially at B3 is where the hit counts, I have to hug Snowman body so I don't get knockback far ahead PLUSSS I have to hit twice as much so that I don't get told "YOU DID NOT PARTICIPATE ENOUGH TO RECEIVE A PRESENT" (which happened 3 times before) and that really upsets me.
