Gems are born with a level of maturity, in simple terms their maturity matches the maturity of an 18 year old person.

The size of a gem is based on their gem. Please look to the show to see the size of your character, and if there is no info then think of your character’s size throughly when making them. (Weight is also based on size.)

As an action you can fuse with another willing being that is of the same race (Gem), requires both characters to have physical contact with another. You and the merged person both share control of this merged being. The abilities and skills of both character are combined to make this fused being’s abilities. Fusing can happen once until you rest or until half a day goes by.

Items can be stored in your gem. The gem acts like a large backpack and it doesn’t bring any strain to the character if the gem is full. The gem can also form weapons based on the character, their skills, etc.

When the character’s hit points reach 1 the character will poof and retract into their gem leading to their body disappearing and leaving behind their gem. If the character’s gem is attacked weither they are proofed or not they with shatter and die. Since the diamonds don’t exist in dnd, poofing = death

Note: Gems can have their gem crack. A cracked gem makes the character’s body deform and glitch.

Note 2: Gem‘s body can’t get scared (unless the gem is emotionally damaged or was previously corrupted), but if a lethal blow is done to their body this poofs the gem. 

Gems are significantly stronger than humans although being similar to them. Strength is based on size and type of gem. (Ex: Quartzes>Rubies>Pearls)

Note: Don’t replace this one if strength is going to be manually set

A character’s gem glows a light equivalent to the glow of a small flame. Light illuminates 7ft in all directions.
