Solar Knife - A dazzling wide bladed golden dagger (+1, +3 when exposed to sunlight). At night, the blade of the Solar Knife emits light as a Light spell. Double damage against the undead.
Aegis Hand - A massive giant-sized gauntlet traced in gold and embedded with a glowing emerald. Functions as a Gauntlet of Ogre Power that does 1d10 damage when used in combat and cannot wield any other weapon. Blows from the Aegis Hand can knock down normal doors with a single blow. Larger reinforced doors may take longer to sunder.
Black Bastion - A stout jet black shield (+2) with the unsettling outline of a face and a pair of fangs at its base. Once per day, the Black Bastion can be struck against the ground to create a Wall of whatever material covers the ground (default is a Wall of Stone)
Mosquito Blade - A thin rapier with a scintillating insect wing hilt. Counts as a +1 magic weapon for the purpose of immunities. Always hits, regardless of armor class, but deals 1 damage plus or minus Strength modifiers for each blow (Thanks to Telecanter for the idea on this one.)
Wingthief Boomerang - A boomerang (+1, +2 vs. flying creatures) made of an unknown bright green wood and inlaid with bronze. Flying creatures hit by the Wingthief Boomerang lose the ability to fly for 1d6 turns.
