This thick leather belt is decorated with a buckle carved from glittering quartz in the shape of a fist. You gain a +3 item bonus to Athletics checks and a +2 circumstance bonus to Athletics checks to lift a heavy object, Escape, and Force Open.
When you invest the belt, you either increase your Strength score by 2 or increase it to 18, whichever would give you a higher score.

You must have a free hand to catch the rock, but you can Release anything you're holding in a hand as part of this reaction.

Failure You take half damage.
Critical Failure You take full damage.
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).
