head into your src/map/battle.c and look for this line
{ "max_parameter", &battle_config.max_parameter, 99, 10, 10000, }
change the 99 to 255
{ "max_baby_parameter", &battle_config.max_baby_parameter, 80, 10, 10000, }
change the 80 to 255 or whatever you want your baby parameters to be
{ "max_third_parameter", &battle_config.max_third_parameter, 20, 0, INT_MAX, }
this is for 3rd job, change the 20 to 255 or whatever u want them to be.
after you do all your changes don't forget to recompile your server or the changes wont occur.
