Centaurion

By the hands of Vister, God of War or a demon lord, you've become a Centaurion, a heavy cavalry unlike any other. You get the following benefits:

• Increase your Strength/Constitution to a max of 20.
• Armoured scales replace your hair, and you develop a 2nd mouth to consume metal and leather, which nourish you as if it were food of equal weight. While unarmoured, your AC = 13 + your Constitution modifier. You can get a shield's bonus as normal.
• Over an hour, you can consume armour that you're proficient with, other than shields. When you do, you don the armour and get its benefits, though your scales remain unchanged. If the armour needs attunement, you attune to it during the process, assuming you have the slots.
• If you consume an extra piece of armour, you doff the previous armour, though you can choose to remain attuned to the armour, retaining any magical benefits it had, such as resistance. If you attune to multiple magic armours that add a magic bonus to AC, you can have up to a max of +5.
