Elder Sequoia Scale Mail (Patreon)

Armor (scale mail), rare (requires attunement by a druid)

This hardy natural mail is made with leather and protected with the large outer shell of an elder sequoia seed cone. You gain a +1 bonus to AC while wearing this armor. In addition, while wearing this armor, you can use your Wild Shape to transform into a mighty evergreen tree. The tree is 5 feet across at its base and can be up to 40 feet tall. Its branches extend up to 10 feet away from its trunk and must be at least 5 feet above its base.

The tree has hit points equal to 5 times your Druid level, AC 20, and vulnerability to fire damage. While you're a tree, you magically retain your normal senses and gain tremorsense out to a range of 30 feet, but your speed becomes 0, and you can only use your actions to shuffle your limbs (as if by a breeze or rustling creature), revert to your normal form, or use your Wild Shape again.

"Was...was that tree always there?"
