Might of the Roc

You have developed traits similar to those possessed by a roc, granting you the following benefits:

• Increase your Strength or Constitution by 1, to a maximum of 20.
• You have advantage on Wisdom (Perception) checks that rely on sight.
• You count as one size larger when determining your carrying capacity and the weight you can push, drag, or lift.
• As a bonus action, you can manifest giant wings, for 1 minute. While you have these wings, you gain a flying speed equal to your walking speed, you have advantage on Strength checks, and you can grapple a creature that is two sizes larger than you. Once you use this feature, you can't use it again until you finish a long rest.
