You can use Stab to get around Narcus's innate fire element but that doesn't affect the bonus damage at all. Saying it's 1:1 is simply incorrect. It doesn't add extra damage to your basic attack. It deals a second hit of magic damage that is also subject to Mag Def and elemental resistance.

Ignoring Lolzy's reasonable request for calcs just makes your argument that it's 'broken' look worse.
