Katana heirloom modifier (mistake?)

[Belmont]

I noticed that the katana only receives +1 pierce damage at masterwork stage compared to other swords which receive +2 pierce damage. Fixing this would bump the katana thrust to 18p and make it slightly more reliable than it is now.

<Fasader> that's intended
<Fasader> it's because weapons with shitty secondary (stab for swords, swing for spears) don't get too much bonus on looming
