Crimson Ritual

You can conduct a 1-hour ritual to attune with non-magical armor. During the ritual, you can change the armor's appearance, and decide what it looks like, including color and style. For the purpose of encumbrance, the original weight is considered halved. All other stats remain unaffected.
If you don't choose the appearance it will automatically be chosen by your otherworldly patron for you.
You may change the appearance of an already attuned item again but must conduct the 1 hour ritual for each item. The item retains its desired glamour style for as long as you are wearing it. If it is removed, it turns back into its normal form. The item resumes the last glamor it had if you put it back on, as long as the attunement remains.
In addition, you may add +1 to the armors AC for medium armor if your Dex bonus is 3 or higher
