Limited Weapon Upgrades

Some weapon upgrades that have special activations and abilities can be activated only a limited number of times per day, as described in the weapon upgrade. This limit is independent of any costs for activating the upgrade. This limit resets during your daily preparations. The limit is inherent to the weapon upgrade, so if an ability that can be used only once per day is used, it doesn't refresh if the weapon upgrade is uninstalled and reinstalled or is installed in another weapon, or if another creature tries to activate the upgrade.

The following traits apply to items.

Consumable: Items with the consumable trait can be used only once. Most manufacturers design these items so the container, syringe, or other remaining materials can't be easily reused to protect their proprietary crafts.
Invested: A PC can wear only 10 magical items that have the invested trait. A character can still gain any normal benefit from using a physical item without investing it, such as using a programmer's plushie as a makeshift pillow.
Magical: Items with the magical trait can be crafted only if a player has the Magical Crafting feat.
Tech: Items with the tech trait can be crafted by anyone, but if they're level 1 or higher, they require the Tech Crafting feat to craft. If a tech item also has the magical trait, they are hybrid items and require the Magical Crafting feat to craft. A level 1 or higher hybrid item requires both the Magical Crafting and Tech Crafting feats to craft.
