Black Blades, Anti-Magic Fields, and Sundering

[Technocrat1011]

Hey folks, quick question about how the three elements of the title interact.

Specifically, the Black Blade of the Bladebound Magus Archetype has a feature called Unbreakable.

Unbreakable (Ex): As long as it has at least 1 point in its arcane pool, a black blade is immune to the broken condition. If broken, the black blade is unconscious and powerless until repaired. If destroyed, the black blade can be reforged 1 week later through a special ritual that costs 200 gp per magus level. The ritual takes 24 hours to complete.

The question is, does the Black Blade retain it's Unbreakable quality while inside an Anti-Magic Field? Or would that quality be suppressed by the AMF, making it vulnerable to sunder attempts as per normal?

(Ex) abilities are not supressed by antimagic.

It would work in an AMF.

Buuuut...

The Black Blade is actually only immune to the broken condition, not damage. In the same way that you can still get killed by HP dmg even if you're immune to the "Dying" condition, a Black Blade can get destroyed by sunder attempts.

Immunity to the broken condition just means that the Black Blade won't take the relevant penalties when its HP is below 50%.
