Ninja Squid

Requirement: Inkling, Dexterity 13 or higher

You can dissolve the structure of your body, allowing you to bury yourself in your Ink and Hide yourself.

While standing in difficult terrain created by an Ink Bolt of your color, you can Hide as a bonus action, and you have advantage on the check. You may remain hidden until you make an attack (including an oppurtunity attack) or exit the inky terrain.

Creatures which enter your inky terrain while you are hidden in it provoke an opportunity attack from you if they are within range of your Swimming speed. As you take the oppurtunity attack, you can choose to move to a space adjacent to them, within your swimming range.

*Can't seem to add a prerequisite for the homebrew race, I'll try to fix it.
