Multiplying the Stat rates of MVP and Mobs

[Eross]

Hi ! Is it possible to multiple the stats of all monsters?? Im trying to create a 255 server and I need to increase the STR AGI VIT INT DEX and LUK (ATK and DEF if possible) to x6 .. to match up with players stats ... Thanks

[Rynbef]

@ErossAt src/map/mob.cpp on line 4544 it begins.

Just change:

  mob->status.str = max(1, stat);

To:

  mob->status.str = max(1, (stat*6));

And the same on the other stats below the other stats.

 

 

Attack change on line 4452 from:

  mob->status.rhw.atk = atk;

To:

  mob->status.rhw.atk = atk*6;

 

 

Defense change on line 4486 from:

   def = cap_value(def, DEFTYPE_MIN, DEFTYPE_MAX);

To:

   def = cap_value(def*6, DEFTYPE_MIN, DEFTYPE_MAX);

 

 

Recompile ur server after. 

Ps: NOT TESTED!!
