[Ghostcannon]

A Glitch that makes DarkHeart (Boss Raider) at Padres del Fuego Beach never hit you while you hit him. Good for lvling grenade or dagger:

There is a two-story house to the right of Darkheart. Get under that house and jump twice and you are now on the roof of the house. Throw grenades at Darheart and you will see that as you hitting him, he just comes throws a dagger at you, switches to his sword and baddabin baddabum! happy lvling up!
