This collection of lacquered rice paper scrolls mounted on flexible bamboo contains a wealth of calligraphic essays and paintings on the art of war, specifically focused on the use of various weapons in warfare and how to tactically deploy warriors using those weapons to the best possible advantage. Consulting the thesis grants a +2 item bonus to Warfare Lore checks. Like most scholarly compendiums, this usage requires holding the thesis in one hand.
The thesis also serves as an extradimensional armory for weapons and ammunition. The thesis has a capacity of 5 Bulk, and only weapons and ammunition can be stored within it. You and others can Interact with the thesis to store or retrieve a weapon or piece of ammunition in it, like a mundane container.

Effect The thousand-blade thesis dramatically unfurls, and the weapons contained within it spring forth and array themselves impressively in the air, floating within easy reach. For 1 minute, you can use a free action to Interact to draw one of the floating weapons. Others can attempt to nab them out of the air, but to do so they must critically succeed at a Disarm check. You can't place weapons back into the thesis until the minute elapses.
Traits
Something of uncommon rarity requires special training or comes from a particular culture or part of the world. Some character choices give access to uncommon options, and the GM can choose to allow access for anyone. Less is known about uncommon creatures than common creatures. They typically can't be summoned. The DC of Recall Knowledge checks related to these creature is increased by 2.
ExtradimensionalThis effect or item creates an extradimensional space. An extradimensional effect placed inside another extradimensional space ceases to function until it is removed.
InvestedA character can wear only 10 magical items that have the invested trait. None of the magical effects of the item apply if the character hasn't invested it, nor can it be activated, though the character still gains any normal benefits from wearing the physical item (like a hat keeping rain off their head).
MagicalSomething with the magical trait is imbued with magical energies not tied to a specific tradition of magic. A magical item radiates a magic aura infused with its dominant school of magic. Some items or effects are closely tied to a particular tradition of magic. In these cases, the item has the arcane, divine, occult, or primal trait instead of the magical trait. Any of these traits indicate that the item is magical.
