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 = Monster EXP * (0.2 + 0.8 * Player level / Total party level) * Party's portion of EXP (see 'When not partied') * 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.)

EXP received by other party members = Monster EXP * (0.8 * Player level / Total party level) * Party's portion of EXP * Party bonus

When not partied:
EXP received by the last hit = Monster EXP * (0.2 + 0.8 * Damage dealt / Monster HP)
EXP received by other damagers = Monster EXP * (0.8 * Damage dealt / Monster HP)
