Tortle Protector

You've mastered using your shell to better protect yourself & others. You gain the following benefits:

• Increase your Str or Wis score by 1, to a max of 20.
• Your natural armor trait now provides a base AC of 18. As normal, your Dex modifier doesn’t affect this #.
• As a reaction when you're forced to make a Dex saving throw, choose any # of creatures w/in 5ft of you. Each chosen creature's considered to've half-cover against any harmful attacks or effects while w/in 5ft of you until the start of your next turn. Once you use this ability, you can’t do so again until you’ve finished a short or long rest.
