This magical armor increases the speed of its wearer. If it is a type of armor that is normally made from leather, it is made from surprisingly tough cloth, and seems diaphanous. If it would normally be made of metal, it is instead made of Mithril.
Speedy Equipping. You can don or doff this armor as an action.
Evasion. Whenever you are subject to a damaging effect that allows you to take half damage if you succeed on a Dexterity saving throw, you instead take half damage if you fail and no damage if you succeed.
Lightfooted. You have advantage on Dexterity ability checks, saving throws, and attack rolls that use Dexterity. In addition, your walking speed increases by 10 feet.
Speed Amplification. If you would apply less than all of your Dexterity modifier to your AC (such as with medium or heavy armor), you instead apply all of it. If you would normally apply all of it (such as with light armor), you instead apply it twice.
The breastplate and shoulder protectors of this armor are made of leather that has been stiffened by being boiled in oil. The rest of the armor is made of softer and more flexible materials.
Notes: Advantage: Dexterity Ability Checks, Advantage: Dexterity Saving Throws, Advantage: Dexterity Attacks, Bonus: Armor Class, Requires Attunement by a creature with a Dexterity score of 15 or higher
