Do you have any opinion about this?

 

[Murilo BiO']

Can you show your battle.c on line 5851? The whole function will be great

This is not the Reflect Damage Skill ID.
Did you changed something in battle.c?

Interesting, Please put it in http://herc.ws/board/tracker/

also do you have any custom code?

Thanks for the replies. The Crash occurrs in "battle.c:5850" function "battle_reflect_damage"

if( (--sc->data[sC_LG_REFLECTDAMAGE]->val3) <= 0 )

The function "battle_reflect_damage" is called from the line "battle.c:5620" (function "battle_calc_weapon_attack")

battle->reflect_damage(target, src, &wd, skill_id);

Also, in this battle.c in the line 4107 (function "Damage battle_calc_misc_attack")

md.damage = md.damage*(1000 + tstatus->mdef) / (1000 + tstatus->mdef * 10) - tstatus->mdef2;

If the value "tstatus->mdef" is -100 you got a crash by division by 0 in this part "(1000 + tstatus->mdef * 10)"

This is the battle.c that has the crash:

battle.c

I'm posting this on bugtracker.

Edit: Cannot start a new Issue in bugtracker.

No, we have not edited this part of the src.
