I have been primarily increasing the level of my characters using the various writs and advice items.
However I have had a character level up through fighting monsters.
I don't understand who gets what exp points when they are awarded. Is it just the character who kills the monster or the whole party?
Based on my own experience and testing, every member in your party will gain the Character EXP when defeating monsters.
I tested this by keeping track of my party member’s experience points and then fighting monsters in the over-world. After defeating a few enemies and re-checking my character, all four members of the party’s experience points had increased
