Dodging melee attacks: hold the left stick to the left or right before the enemy attacks to dodge it. There isn't a timing window, just be holding left or right before the enemy hits you. To dodge a series of melee attacks, hold the left stick on one direction before the enemy attacks. Then shift to hold the left stick in the other direction, alternating between sides. Never dodge in the same direction more than once or the sequence will fail.

Stomp corpse - after defeating an enemy, press the triangle button to stomp on their body and trigger item drops. Gather any dropped pick up items.
