Dolmenwood: Fairy Blades

I've started work on the next Dolmenwood Adventures module: a scenario for 1st or 2nd level characters revolving around a fairy banquet, dance, and market. Therefore, I'm coming up with information on what one can buy at a fairy market -- a fun project! Here's a little preview: the weapons that are available at one of the stalls.

The Blade Seller

Blades crafted by fairy smiths (known to be magical). By their nature, they carry a +1 enchantment and another glamour (see table)*. There is no way of perceiving a weapon’s glamour before purchase.

d12	Type (cost, damage)	Appearance	Glamour**
1	Knife (100gp, 1d3)	Delicate spiderweb engravings	Inflicts +2 damage to mortals.
2	Dagger (200gp, 1d4)	Fine tree branch lattice inlays of gold	Animals are suspicious of the owner (-2 to reaction rolls).
3	Dagger (200gp, 1d4)	Crackles with blue sparks when touched	When in darkness, glows like the moon.
4	Shortsword (400gp, 1d6)	Glistening with dewdrops	Once drawn, cannot be sheathed unless blooded.
5	Shortsword (400gp, 1d6)	Appears old and battered, but is actually perfectly sharp	3-in-6 chance of the owner not being recognised at a casual glance.
6	Rapier (400gp, 1d6)	Engraved with fine images of unicorns at play	Become obsessed with thoughts or mortality and entropy.
7	Longsword (600gp, 1d8)	Rimed with frost	The owner’s natural scent is replaced with that of blossom or cinders.
8	Longsword (600gp, 1d8)	Inlaid secret runes of fairy silver	+2 to saves vs cold.
9	Scimitar (600gp, 1d8)	Wreathed in moonlight	The owner suffers from sleeping irregularities -- sleeping for exactly 2d6 hours (roll per night). (This may be too little or too much.)
10	Broadsword (600gp, 1d8)	Opalescent	See in moonlight as if it were daylight.
11	Bastard sword (800gp, 1d8/2d4)	Pitch dark metal	Alignment shifts one step toward Chaotic, over the course of a month.
12	Two-handed sword (1,200gp, 1d10)	Perpetually occluded by shadows	The owner develops a taste for the refined and decadent. (One who already has such tastes may tend toward depravity.)

* The proprietor says that “mortals call them magical”, but fairies themselves do not conceive of items such as these as being enchanted.

** True fairies (e.g. elves, grimalkin; not including demi-fey) are unaffected by these glamours.
