Weight light
This deep red cloak fits lightly about your shoulders, and the edges perpetually twitch slightly, as though caught in a breeze. The cloth feels smoother than silk, rippling and swaying like liquid when in motion. You feel a lively energy infusing your arms and legs. You gain a +3 item bonus to Acrobatics and Stealth, and a +2 circumstance bonus to AC against attacks from reactions triggered by your movement.
When you invest the cloak, you either increase your Dexterity score by 2 or increase it to 18, whichever would give you a higher score.

Traits
Anything that doesn't list another rarity trait (uncommon, rare, or unique) automatically has the common trait. This rarity indicates that an ability, item, or spell is available to all players who meet the prerequisites for it. A creature of this rarity is generally known and can be summoned with the appropriate summon spell.
ApexWhen you Invest an Item that has the apex trait, it improves one of your ability scores, either increasing it by 2 or to a total of 18, whichever grants the higher score. This gives you all the benefits of the new ability score until the investiture ends. An apex item grants this benefit only the first time it's invested within a 24-hour period, and you can benefit from only one apex item at a time. If you attempt to invest an apex item when you already have one invested, you don't gain the ability score increase, though you do gain any other effects of Investing the Item.
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.
TransmutationEffects and magic items with this trait are associated with the transmutation school of magic, typically changing something's form.
