Mob spond place question

hey guys hawe stupid question i want to add new mob-boss who care i open mob.csv and what i see is

Mob_pX1,Mob_pY1,Mob_pZ1,Mob_pX2,Mob_pY2,Mob_pZ2,Mo bID,Mob_Count

i know that i nead add position x y z
that ok but what i nead to pot in Mob_pX2,Mob_pY2,Mob_pZ2?

thanx for undestanding

if u want to add bosses i would suggest to add them into obelisk.ini which is alot easier.
if u want to add mobs then u come to Mob_pX2 this defines a second location which means that the boss will spawm anywhere between 2 of this places.

Big thanx :)
