// Experience for a kill multiplied by the victim's level
smrpg_exp_kill "50"
// Maximum experience a player can ever earn for killing someone. (0 = unlimited)
smrpg_exp_kill_max "50.0"
For now, you only get 50 exp per kill whether you're VIP or not. The exp you get is multiplied by 1.5 but concerns only the damages you do to the zombies.
// Experience for hurting an enemy multiplied by the damage done
smrpg_exp_damage "0.15"
0.15 is for regular players but you, as a VIP has 0.225.
