Personality System Data Collection [WiP]

Might be obvious, but you don't get any Ambition if you don't damage the boss monster[s] involved.
(Mainly noted because you don't necessarily get the 76 Ambition from Kenta PQ unless you attack them both)

If you're within 5 levels or higher leveled and the boss, and your party hits it, even if a non-party member kills it, you'll leech the ambition. I learned this while farming ambition off Leviathans pre-chaos with a friend.
