Gorgon Transformation

As you have saved the ancient Hydra from inprisonment by an unkown cult she gave you a fragment of her power as her blessing.  

As an action you can transform into a hybrid serpent form. From your waist down your body transforms into a 4 -5 meter long serpent with dark scales and a hardened tail. Your hands transform into sharp claws.

Each transformation requires a wisdom or constitution saving throw with a DC of the GMs choosing. It may differentiate because of inner or outer circumstances.
You cannot cast or concentrate on spells in hybrid form. Any armor and nonmagical items you wear beneath your waist, merges into your hybrid form. The GM may decide if the armor or an item is unsuitable to merge. While transformed you can use weapons  and equipment as normal, unless specified elsewhere.

You gain proficiency in the following attacks and traits: 

• Claw attack: Upon hitting you deal 1d8 slashing damage instead of bludgeoning damage with your unarmed strikes. Any 1  you roll for the slashing damage can be rerolled once.
• Tail whip: As an unarmed strike you can attack with the end of your tail. It has range of 10 ft and deals 1d8 bludgeoning damage.
• Constrict: As an action you can attempt to grapple a creature of medium or smaller statue. You can only grapple one creature at a time. Upon successing you can use your bonus action to automatically deal 2d6 bludgeoning damage. the creature can attempt to get free as by the rules.
• You can use your bonus action to hide.

Transformation flaws

• You are allergic to any gold. Talk to you GM as to how this shows in your game.
• Moon sensitivity: As many Hybrid Creatures your power is connected to the phases of the moon. 
• Reptillian Psyche: Your view of the world and creatures in it may change. Upon the GM's discretion you may look and react indifferent and heartless towards helpless creatures or the suffering of others. This may be connected to the moon cycle and your current health state.

The transformation is far from finished. Many changes may come in your future as a serpent hybrid.
