level penalty pre-renewal

[Jinzo7]

I would like to add a level penalty to my pre-renewal server, or at least guarantee a bonus, when the character eliminates a monster stronger than him.

Probably can be accomplished by just defining RENEWAL_EXP:

/// Renewal exp rate algorithms
/// (disable by commenting the line)
///
/// Leave this line to enable renewal item exp rate algorithms
/// While enabled a special modified based on the difference between the player and monster level is applied
#define RENEWAL_EXP

Then set up level_penalty.yml in db/import.
