To defeat the 2nd boss, pick up the poison staff in the map before. When you meet the boss, he'll rush you first so move to the bottom of the map to avoid it. Then stay there still your screen rumbles then move up. He'll throw a spear at you so avoid that then pick up the spear. You'll drop the staff so go to the middle and stay near the staff. When he charges at you, throw the spear at it and it'll get stun. Pick up the staff quickly and you can hit it about 4 times before it stomps the ground so jump to avoid that. Use the A attack for the 4 hits instead of the S attack as there is poison effect. Repeat until its dead.
