Crystal Shard

The Crystal Shard is a consumable that grants the user a forcefield lasting 10 seconds upon use.

Appearance
The Crystal Shard is a shard of a blue crystal, presumably the same as the ones present in Crystalline Caves.

Tips

 * The Crystal Shard can be used in boss battles as the 10 second forcefield lets you deal a ton of damage with no cost of health, especially valuable if you also have Piercing Blade and you're up against The Hoarder, which is the only boss which wields a sword.
 * It can also be used in an emergency to protect the player in dire situations.
 * The Crystal Shard is extremely useful in tight corridors and bullet-saturated rooms, as it lasts long enough for you to kill plenty of troublesome enemies.
 * If the droids you're up against have the Piercing modifier, the contact damage from those droids will bypass your forcefield. Instead, use ranged weapons or utilize Blocks.
 * If Piercing Gunner Droids/Rapid-Fire Droids are blocking you with bullets then the Crystal Shard is still viable, as bullets never deal piercing damage and unless it is difficult to engage in close-ranged combat without taking contact damage you won't lose Blocks.

Trivia

 * The Crystal Shard is similar to some other forcefield based items, such as the Geode or the Crystal Torch.
