Marenian Tavern Story: Patty and the Hungry God

At the end of each fight there is a Gained EP tab that shows how much experience was received. There are 5 elements Phys, Fire, Water, Wind and Earth. If you go into the menu then Skills tab any skills marked ??? Will show the elemental type, Needed EP, and Gained EP for each skill. Only the 3 active characters gain EP and they must be alive at the end of the fight. All EP gained is distributed equally to all unlearned skills.
