TEXT:  
  Elf Subrace 
  At the GM's discretion, you have access to more subraces 
  for elf characters, in addition to the subraces in the Player's 
  Handbook.  
  Santa’s Elf 
  As an elf that hails from the far north, you are often 
  mistaken for a very tall gnomes, likely because of your, 
  persistent cheerfulness, smaller than average stature, and 
  penchant to make toys for good little boys and girls. 
  Santa's Elf Traits 
  As an elf from the far north, you have the following traits:  
       Ability Score Increase. Your Charisma score increases 
  by 1. 
       Cold Resistance. You have resistance to cold damage. 
       Slight Stature. You suffer no penalty for squeezing into 
  a space that is only large enough for a creature that is one 
  size smaller than you. 
       Holly Jolly. You and all friendly creatures within 5 feet 
  of you can add your proficiency bonus to Wisdom saving 
  throws.  
   
   
   
   
   
       Toymaker. You have proficiency with artisan’s tools 
  (tinker’s tools). Using those tools, you can spend 1 hour  to 
  construct a toy, which is in the shape of an animal, monster, 
  or person, such as a frog, mouse, bird, dragon, or soldier. 
  You can build any toy of the following types, each of 
  which has AC 5 and 1 HP:  
  Clockwork Toy. This toy requires 10 gp worth of materials 
  to construct. When placed on the ground, the toy moves 5 
  feet across the ground on each of your turns in a random 
  direction. It makes noises as appropriate to the creature it 
  represents. This toy ceases to function after 24 hours 
  (unless you spend 1 hour repairing it to keep the device 
  functioning), or when you use your action to dismantle it; 
  at that time, you can reclaim the materials used to create 
  it. 
  Plush Toy. This stuffed toy squeaks loudly when it is 
  squeezed or when a string on its back is pulled, making a 
  noise reminiscent of the creature it represents. 
  Wooden Toy. This toy, affixed with wheels, can be set to 
  rolling in a direction as an action. It moves 10 feet in that 
  direction on each of your next three turns, making noises 
  as it moves.
