Ti-a zis Kidro mai sus ... in Instancebase.cpp (client)
In void CInstanceBase::SetSash(DWORD dwSash)
Cauta:

	float fSpecular = 65.0f;
	if (dwSash > 87000)
	{
		dwSash -= 2000;
		fSpecular += 35;
		
		m_dwSashEffect = EFFECT_REFINED + EFFECT_SASH;
		__EffectContainer_AttachEffect(m_dwSashEffect);
	}

Adauga sub:

	if (dwSash == VNUM)
	{
		fSpecular = 0;
	}

Inlocuieste VNUM cu id-ul de la esarfa (codu de la item).
