race features:
Children of the Storm: As children of the mighty Storm Giants, you have gained their resistance to lighting.
Lightning Quickness: Your base walking speed increases by 5 feet.
Storm's Fury: If a creature within 30 feet of you hits you with an attack, you can use your reaction to strike at them with a bolt of lightning. The creature must make a Dexterity saving throw. On a failed save the creature takes damage equal to 1d6 + your Wisdom modifier, or half as much on a successful save. The creature has disadvantage on the save if it is wearing metal armour. You can use this trait a number of times equal to 1 + your Wisdom modifier (minimum 1) per long rest.
Storming Weapon: If at least one of your hands is free you can use your action to create a weapon made of wind or lightning, it lasts 1 minute or until you dismiss it as a bonus action. You are proficient when using these weapons. You may use your Wisdom modifier for your attacks with these weapons. These weapons do not count as magic weapons for purposes of overcoming resistance. A weapon created using this feature cannot be wielded by another creature and dissipates into mist when a creature tries to do so. Once you create a weapon with this feature, you cannot do so again until you finish a short or long rest.
