Phantasmal Weapon

From LSWiki

This is a shimmering iron longsword with a weird translucency to it, seeming to tremble and waver when it is not being given one's
full attention.  The quality of its craftsmanship is exquisite.  There is a small, barely-visible image on its surface that looks
like the face of a wolf with the eyes of an eagle.  This is a phantasm weapon, a mote of power belonging to Doppel, the god of
Illusion.  It is a semi-solid illusory substance that responds to thought and will; one need only visualize a weapon form and it
will seem to alter itself accordingly.  The precise extent of the variety of implemented weapon types that a Doppelweapon can
mimic is not commonly known; many individuals have claimed to have compiled the complete list, only to discover a new form shortly
thereafter.  It appears to be composed of a few thin streamers of shimmering haze and a few thin wisps of shimmering radiance. 
You estimate its value at about three hundred twenty gold.  
It is in perfect condition.  
It looks about a fifth of a dimin wide and fourteen dimins long.  It weighs about five hundred one thousandths of a dekan.
After a moment, the knowledge that the shimmering iron phantasmal longsword is composed of sixty-five percent dweomer and thirty-five percent iron drifts into your mind like a long-forgotten memory.

• Can assume almost any weapon form. Doing so uses creative energy.
• Deals partial Goetia damage.
• As they are manifestations (not real), they are easily destroyed by antimagic effects such as Bezhuldaar eyebeams.
• Weapon craft is determined by effective skills in Imagination, Weapon Lore and probably some other ones (this is wild speculation with zero confirmation).
• Whatever the skills may be, the shaper's current creative energy at the time of visualizing seems to play a significant role in the final quality. Possibly this is a modifier to whatever skills contribute or added alongside them or something else?
• Weapon forms are most likely simply drawn from the ones intrinsically known to you, but it is true skills like weapon lore would help with this.
• One can reliably be obtained in Sanctuary in the temple of Doppel. Appears quite rarely as a randomload weapon.
