EXP Splitting

 Spoiler

Leech conditions: Only one of the following must be met in order to share a cut of party EXP
1. Deal at least 1 damage to the monster.
2. Be within 5 levels of the monster.
3. Be within 5 levels of a party member that fulfills 1 or 2.

EXP received by the highest damager = EXP to be split * (0.2 + 0.8 * Player level / Total party level) * Party bonus
EXP received by other party members = EXP to be split * (0.8 * Player level / Total party level) * Party bonus
(Total party level = sum of the levels of all players that satisfy leech conditions. When not partied, you count as your own party, i.e. you get all the EXP. This is assuming your party deals all the damage. If not, "EXP to be split" is the portion of EXP your party would receive according to the "When not partied" formula below.)
(In order words, 20% is given to the highest damager, and the other 80% is split proportional to the levels in the party.)

When not partied:
EXP received by the last hit dealt = Monster EXP * (0.2 + 0.8 * Damage dealt / Monster HP)
EXP received by other damagers = Monster EXP * (0.8 * Damage dealt / Monster HP)
(In order words, 20% is given to the person or party that dealt the last hit, and the other 80% is split proportional to damage.)

This is no longer true from my observations and testing.

EXP received when partied = EXP to be split * ( 0.4 * Player level / Total party level + 0.6 * Damage Delt / Monster HP ) * Party bonus
EXP recieved when not partied = Monster EXP * ( Damage dealt / Monster HP )

The person who does the most damage no longer gets an inherent bonus to their exp; you now get exp based on how much damage you did. When a party gets the last hit, they no longer get the 0.2 bonus to their exp either.

I don't have any screenshots, but I did do some testing. I was in a party with a friend at Blue Kentaurus and I had him kill some of them. I got 639 exp. When I did small amounts of damage to the Kentaurus (things like Ice Splitter, Flame Thrower, and Recoil Shot), I seemed to get more exp based on how much damage I did. Then I did what looked like about half of their HP and had him kill it. It gave us both pretty much even exp (noting that the 0.2 bonus isn't there anymore). Lastly, I disbanded the party and reduced a Kentaurus' HP down to 1 with Flamethrower and had him kill it. I got the full 1600 exp while he got 1 (further noting the lack of 0.2 bonus for either a partied or unpartied kill).

This is actually nice balancing. No longer does the person who happens to be slightly stronger than the rest of his party take most of the exp from it, and no longer does the party lucky enough to get the last hit on a boss steal all the exp from it. With this formula it's far more beneficial to have as strong a party as you can assemble rather than a party of people who are just a little bit weaker than you.
