Your Constitution score increases by 2, and your Strength score increases by 1.

A dragonfein, being a cousin of true dragons, shares their long life. It matures at the age of 5 and can live for up to 160 years.

Most dragonfeinen are pleasant in demeanor, commonly being neutral leaning towards good. Extreme and evil alignments are incredibly rare, but not unheard of.

In their natural form, dragonfeinen are commonly a bit larger than a house cat, with their tail equal length to their bodies, they stand to about a foot at the shoulder and are often 3-4 feet long. Your size is Small in your natural form, and Medium or Small (your choice) while in your humanoid form.

In your natural form, your base walking speed is 20 feet and you have a flying speed of 30 feet. In your humanoid form, your base walking speed is 30 feet and you have no flying speed.

You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can't discern color in darkness, only shades of gray.

You may be the smallest of the dragons but you are still a dragon. Your creature type is dragon.

You are proficient in the Perception skill. While in your natural form, you also gain advantage on Wisdom (Perception) checks that rely on sight, hearing, or smell.

You can speak, read, and write Common and Draconic while in your humanoid form. When you are in your natural form, you are unable to speak, but can still understand any languages you know.

You have a stinger that you can use to make unarmed strikes. When you hit with it, the strike deals 1d4 + your Strength modifier piercing damage, instead of the bludgeoning damage normal for an unarmed strike. In addition, when you hit a creature with this attack, you may attempt to poison the creature, forcing them to make a Constitution saving throw. The DC for this saving throw is equal to 8 + your proficiency bonus + your Constitution modifier. On a failed save, the target becomes poisoned for 1 minute. The target can repeat the save at the end of each of its turns to end the effect. You can use this poison a number of times equal to your proficiency bonus before you must finish a long rest to use it again.

A Dragonfein has advantage on saving throws against spells and other magical effects that would alter its form.

As an action, you can change your appearance to that of a humanoid, though none of your game statistics (other than speed) change. Your humanoid form is able to use weapons, armor, and items that you otherwise could not use, but you also lose any semblance of your natural form (including your wings and stinger). This humanoid form is consistent and retains the sex and gender that you have in your natural form, but otherwise the appearance (including clothing, hair style, etc.) is up to you. Any equipment you are wearing or carrying isn't transformed when you transform back into your natural form.

You stay in this humanoid form until you use an action to revert to your true form or until you die.
