Well here I post the Deep Gnome Tratits: (from the Elemental Evil supplemet)
Ability Score Increase.
Your Intelligence score increases by 2, and your Dexterity score increases by 1.
Deep gnomes are short-lived for gnomes. They mature at the same rate humans do and are considered full-grown adults by 25. They live 200 to 250 years, although hard toil and the dangers of the Underdark often claim them before their time.
Svirfneblin believe that survival depends on avoiding entanglements with other creatures and not making enemies, so they favor neutral alignments. They rarely wish others ill, and they are unlikely to take risks on behalf of others.
A typical svirfneblin stands about 3 to 3½ feet tall and weighs 80 to 120 pounds. Your size is Small.
Your base walking speed is 25 feet.
Your darkvision has a radius of 120 feet.
You have advantage on all Intelligence, Wisdom, and Charisma saving throws
You have advantage on Dexterity (stealth) checks to hide in rocky terrain.
You can speak, read, and write Common, Gnomish, and Undercommon. The svirfneblin dialect is more guttural than surface Gnomish, and most svirfneblin know only a little bit of Common, but those who deal with outsiders (and that includes you as an adventurer) pick up enough Common to get by in other lands.
