//       all default values should be epic-level compatible


// this will modify global xp output similar to the module xp-slider
// higher value = more xp
// PC needs to kill a combined CR of (PC-LEVEL * 1000) /  PWFXP_GLOBAL_MODIFIER
// on average to gain a level. use this as a rule of thumb and base to calculate
// the more advanced modifiers
//
// e.g. a level 10 needs to kill 100 CR-10 mobs to level (aprox.) using default 10.0 global modifier
//      he will only need 50 CR-10 mobs if you set it to 20.0
//      setting this to 1000.0 = he only needs one CR-10 mob to level
//
// you can further scale the leveling progress more precisely with the PWFXP_LEVEL_MODIFIERS constant
// just continue to read my comments...

//
// you can make the first few levels an easy catch but make the last a pain to reach.... very flexible now

// (not counting group bonus or other advanced modifiers)
//
// modifier explanation:
//
// a value of 1 (01.000) means no xp change.
//
// the actual xp bonus/penalty in % = (modifier - 1) * 100
//
// use value < 1.0 to reduce the xp
