Please Add Unarmored Defense to Customization

[MondaysAreShit]

Motivation / Use Case:
I'm always frustrated when I create a new character class in a tabletop RPG, and I'm not allowed to choose unarmored defense as an option. Unarmored defense is a popular feature in many RPG systems that allows characters to use their natural abilities to defend themselves instead of relying on armor. It's a fun and immersive way to play and can add depth to character creation.

Expected Behavior:
When creating a new class in an RPG system, players should be allowed to choose unarmored defense as an option. This would involve creating a set of rules for how unarmored defense works in the context of the game, such as how it interacts with other abilities and how it scales as characters level up.

Other Information:
Some alternative solutions could include allowing unarmored defense only for certain classes or limiting it to certain types of characters, such as those with high Dexterity or Constitution scores. However, these solutions can limit player creativity and reduce the overall fun and immersion of the game. Allowing unarmored defense as a standard option for all classes would provide players with more choices and help to create a more diverse and interesting game world.

Actively working on opening up a custom AC solution. No timeline yet but it's an open branch now.
