Veiled Illusionists, Phantasmal Killer and Persistent Spell

A high level character with the Full ten levels in the Veiled Illusionist PrC casts Phantasmal killer whilst using the Naga veil ability.

By my interpretation of what happens, The target must make up to 2 Will saves (taking the lowest) before making the Fort save to not take damage or die as per the rules of Phantasmal Killer, Is this correct?

Second Scenario, the high level Veiled Illusionist cast Phantasmal Killer again, but with the Persistent Meta-magic feat applied, by my interpretation, the victim must make 2 Will saves (taking lowest), followed by 2 Fort saves(taking lowest), is this correct?

Third Scenario, the high level Veiled Illusionist cast Phantasmal Killer, with both the Naga Veil ability and the Persistent Meta-magic feat applied, would the victim have to make 3 Will saves (taking lowest) followed by 2 Fort saves (taking lowest0 to not die as per the spell, is this correct?

Thanks for the assist, Ninja.

"cast Phantasmal Killer again, but with the Persistent Meta-magic feat applied, by my interpretation, the victim must make 2 Will saves (taking lowest), followed by 2 Fort saves(taking lowest), is this correct?"

If I understood it right, Persistent Meta-magic feat grants spells second chance to affect the target.

If you target succeeded on first roll it has to make a new roll. Essentially it rolls 2 times, if it failed on both it's affected by the spell. In this case, being affected by the Phantasmal Killer means it failed to perceive that it's illusion. Second Fort save is additional and isn't affected by Persistent Meta-magic feat because target is already under effect of Phantasmal Killer.

But this is just a guess and my logic. I am not sure it's correct.

Is this correct?

Second Scenario

is this correct?

Third Scenario

is this correct?

With the last Will save being at +4, yes.
