Serpentine Stances

Through serpentine flexibility, you can flow between combat stances that emphasize stealth or striking power.
As a bonus action, you can assume one of the following poses. You remain in that pose until you switch to another or return to a normal stance (no action required).

Slither Pose

• Stealth: Add your proficiency bonus again to all Stealth checks.
• Attack Rolls: Subtract twice your proficiency bonus from all attack rolls.
• Space: You occupy a 10-foot by 5-foot space (2×1 squares).

Striking Pose
You rise high, stretching your body into a towering, aggressive posture.

• Height: about 8 feet tall.
• Attack Rolls: Add twice your proficiency bonus to all attack rolls.
• Armor Class: Reduce your AC by an amount equal to your proficiency bonus.
• Movement: Your walking speed is halved.
