Epic Lizardfolk

Beneath your hardened scales beats the heart of a primal being. You have been shaped by nature into the perfect survivalist, never unarmed and always ready for action. Your racial traits are replaced or altered to include the following benefits.   Chameleon Skin. As a bonus action you can turn invisible. This effect ends if you move from your space or take any action.   Improved Natural Armor (Replaces Natural Armor). When you aren't wearing armor, your AC is 17 + your Dexterity or Constitution modifier (your choice).   Primal Arsenal. You can spend 1 hour of strenous activity attaching bits of bone and other material harvested via your Cunning Artisan feature to a melee weapon or an extremity you would use to make an unarmed strike. When you do so, the next ten successful hits with that weapon or extremity deal an additional 1d4 piercing damage.
