Fix frystaxe from Erin's Auraeyl

[Safairette]

Changes

• Nerfed frystaxe's stats to be mildly above the Royalty axe in effectiveness, instead of the current monosword-tier stats.
• Changed harpoon to be a fixed market value of 270 (original vanilla value), as the increased cost made it too expensive for certain pawnkinds.

References

Reasoning

• It's a basic medieval tech weapon.

Testing
