OK Experience is cut in several parts. (Thx to Foxbat for the 1.09B Offset and to pmpch for the partyBonus info)
1) PART I Monster Birth
Levels.txt Monstats.txt and Monlvl.txt are used to compute Base Expérience.
Then The "Players X" bonus
Exp=Base+Base*(NbPlayer#-1)/2
2) PART 2 Monster Death
Party bonus
EXPGroupe=base+Base*(Nbplayer#inpartyinthesamemap-1)*(89/256)/100
Sharing the Xp
Each member gains
Exp=ExpGroupe*CLVL/(Sum of the CLVL)
3) PART III Personnal Bonus / malus
Bonus
Exp=Exp+Exp*(BonusShrine+BonusObjet%)/100
Malus
MLVL Versus CLVL(2 cases Player CLVL<25 and Player clvl>=25)
High CLVL Malus
Exp=Exp*ExpRatio/1024
