RPG Insanity

Hello guys how you doing...

I have been trying to search for an item called Sword fragment that used in Add effect on weapons to add STR points on them...anyone have a clue on which mobs dropping it and the place to farm for it??

 

I never finished this game; so, there are likely others. But it looks as if it basically an ogre-type mob drop:

Ogre - Adante Town vicinity

Mad Ogre - Guild vicinity

Berserker - Lightoria Tower.
