Antilife Flower

A DC 17 Strength check is required to pluck this flower from where ever it is.  When this flower is pluck it drives the tip of it's stem into the creature's hand.  A new flower blooms from the back of that creature's hand and the original flower quickly wilts away.  This flower will shimmer with Abjuration magic if detect magic is used on it.

This flower has four charges.  You can use a bonus action to pluck a petal from the flower.  When a petal is plucked it provides a shimmering barrier similar to the Antilife Shell spell in the shape of a shield.  The barrier lasts for 1 minute and provides the user +3 AC.

The flower stays alive by feeding off of the host's life force reducing the host's maximum HP by 20.  The creature can spend a bonus action and 5 HP to allow the flower to regrow one petal to a maximum of 4 petals.

If the player is attuned to three items at the time of plucking this flower they must choose one item to un-attune from.
