Emergency i need help !

I'm in king's peak quest of ascending the mountain . im stuck at the second mandatory myth challenge (the bow one odeysius i think) but i can't do it because of my controller ! Analog drift cannot let me aim correctly and the arrow always goes up . i heard that there is an upgrade that let's you control the arrow's speed ? That might help but the problem is no fast travel point nearby . Im so frustrated , if there is one tell me please
