This single magical bracer is constructed of thick animal hide.  Brown and white fur encircle the outside edge of the top and bottom openings. The rest is supple but thick brown leather. 

Runic symbols of the Jotun language (the language of Giants and Goliath) are branded into the bracer along its length.    The inscription loosely translates to "the cannon is me". 

When the wearer of this bracer activates its magical energy, a quick burst of runic strength surges through their arm (creating small visible arcs of lighting that jump across the users skin, sometimes singeing exposed hair or other highly flammable materials).  This allows the wearer to occasionally perform fantastic feats of strength with that particular arm. 

This bracer has one magical charge, (replenished during a long rest).  This magical charge can be used to perform one of the following effects. 

• Boundless Hurl: 
  You may treat any object up to 1/2 your body weight as a thrown (ranged) improvised weapon attack with the following stats: +8 to hit, range is 80/120. On hit, roll 3d6+STR modifier bludgeoning damage.  
  
  
• Feat of Giant Strength: 
  Take advantage on a Strength check, save, or contest.  A value of 18 or 19 is also considered a critical success.  At discretion of the DM, player may also use this ability for an Athletics check. 
  
  
• Gargantuan Strike:
  Take advantage on an attack with a melee weapon.  A value of 18 or 19 is also considered a critical success. On hit, add an additional 1d6+2 damage of the weapon's damage type.
