I'm back with another a blind legend guide. So lets begin.
The goal of scene 15 is to deflect the archer's poisoned arrows with your blade and fight two monsters.
So lets begin.
Follow Louise till you reach the section where the game plays on auto. Louise will get shot in the leg and then Blake automatically will draw his sword.
In order to block the arrows you will need to swipe in the direction the arrow is coming from. Using your shield will not do anything, unless you would like to sit there with you shield up all day. LOL
Anyway, here's an example. If an arrow were to come from the right side, I must swipe right to deflect it. Once you have deflected all the arrows, you must fight a few monsters.
IN hard core, the arrows vary in speed and damage. So be careful.
Hope this helps.
