You have a second set of arms with which you can grasp things.  Using your second set of arms, you can lift a number of pounds equal to five times your Strength score. You can use them to do the following simple tasks: lift, drop, hold, push, or pull an object or a creature; open or close a door or a container; grapple someone; or make an unarmed strike. 

You can wield one-handed weapons with your second set of arms, but not two-handed weapons or shields.  When using the attack action, you can choose which arm(s) make the attack.  

When you take the attack action to make a melee attack, you can use your bonus action to strike out with additional melee weapons you are carrying that have the light property.  If you take the Dual Wielder feat, the weapons do not need to have the light property.  Striking out with a second weapon carries no penalty.  Striking out with three weapons places a -5 penalty on all three attack rolls.  Striking out with four weapons places a -8 penalty on all four attack rolls.  You can attack different targets with each attack.  

If you use all four of your arms to grapple a target, the target has disadvantage on Strength (Athletics) or Dexterity (Acrobatics) checks made to escape your grapple.

One ability score of your choice increases by two, and a different ability score of your choice increases by 1.

Aarakocra reach maturity by age 3. Compared to humans, aarakocra don’t usually live longer than 30 years.

Most aarakocra are good and rarely choose sides when it comes to law and chaos. Tribal leaders and warriors might be lawful, while explorers and adventurers might tend toward chaotic.

Aarakocra are about 5 feet tall. They have thin, lightweight bodies that weigh between 80 and 100 pounds. Your size is Medium.

Your base walking speed is 25 feet.

You have a flying speed of 40 feet. To use this speed, you can’t be wearing medium or heavy armor.  If you are carrying more than 5 times your Strength modifier in weight, your flying speed reduces to 20 feet.  If you are carrying more than 10 times your Strength modifier in weight, your flying speed reduces to 0 feet.

Your talons are natural weapons, which you can use to make unarmed strikes. If you hit with them, you deal slashing damage equal to 1d4 + your Strength modifier, instead of the bludgeoning damage normal for an unarmed strike.

You can speak, read, and write Common, Aarakocra, and Auran.
