I'm sorry to necro an old thread, but I recently started screwing around with an emulator server again and have recently ran into difficulties using the mod_effect_value function again, namely for heal over time spells.

Here is my rough draft of my mod_effect_value function I have been playing around with to try to iron out bugs.

Code:
int Mob::mod_effect_value(int effect_value, uint16 spell_id, int effect_type, Mob* caster) 
{ 
	if (IsDamageSpell(spell_id) )
	{
		if (!(this == caster))
		{
			effect_value *= (caster->GetINT() / 100.0);
		}
	}
	else if (IsEffectHitpointsSpell(spell_id) || IsHealOverTimeSpell(spell_id))
	{
		effect_value *= (caster->GetWIS() / 100.0);
	}
	else if (IsRuneSpell(spell_id))
	{
		effect_value *= (STA / 100.0);
	}
	return(effect_value); 
}
After some testing, it appears that Nukes, DoTs, lifetaps, and direct heals seem to be working as intended. Also, to get IsDamageSpell to include DoTs as well, I just modified the function like so...
Code:
bool IsDamageSpell(uint16 spellid)
{
	for (int o = 0; o < EFFECT_COUNT; o++) {
		uint32 tid = spells[spellid].effectid[o];
		if ((tid == SE_CurrentHPOnce || tid == SE_CurrentHP || tid == SE_BardAEDot ) &&
				spells[spellid].targettype != ST_Tap && //Removed && spells[spellid].buffduration < 1 after ST_TAP
				spells[spellid].base[o] < 0)
			return true;
	}

	return false;
}
I included that just in case that check was more important than I realized.

My problem is, whenever I cast a heal over time spell, I get the following exception when debugging the zone in Visual Studio
Code:
First-chance exception at 0x01B237A0 in zone.exe: 0xC0000005: Access violation reading location 0x00000000.
Unhandled exception at 0x01B237A0 in zone.exe: 0xC0000005: Access violation reading location 0x00000000.
Also, in the crash log there is the following
(I shortened the path to my executables and source just for clarity since they're long)

Does anyone have an idea what these errors mean other than some filename is not available? I'm just confused why this error only occurs on heal over time spells as well. It seemed to be crashing on the line which causes no issues on regular heals.
Code:
effect_value *= (caster->GetWIS() / 100.0);
