Castlevania: Lords of Shadow

Mountain Fortress
Kill the ogre without getting hit: This one is pretty annoying. Stay as far away from his hand at the start of the encounter as possible, he will try to grab you and that'll result in a failed trial. Once you start the full fight, watch his hands, left hand equals run to the right as fast as possible, right means run left. Do not stay close to him, his elbow will clip you and hurt you. Do the QTE once he has low enough health or use this moment to stock up on orbs if you want that's to the left of the bridge. Be very careful when you have fully blinded him, he will start slamming down with open palms. Use Shadow magic to help you lower his health.

The Crow Witch

The Crow Witch's Children: You have to kill the crow witch without killing no more than two of her children. As the fight starts off, the game will focus on the witch as she coughs up the eggs. You CAN NOT let no more then TWO eggs hit the ground, any more then two will result in a failed trial. When she starts coughing them up, starting mashing and spinning the left analog stick, do not stop this until she is dazed. Do the QTE while she is dazed to move on. Now you will have one or two children to fight, no matter what you will have to kill them, the Crow Witch circles around endlessly if you don't kill the kids. Remember, no more then one or two should be killed. Do the egg tossing QTE again and you should be in the clear as long as no eggs hit the ground.
