The Winter Rose’s Marionette

Gwen's Prestige 5 Feat
Gwen has learned the art of mixing her Hexblood with her wooden figurines to bestow the mark of the Winter Rose. You can store magical ink in any of your figurines that can be used to apply the ink for tattoos through small, magically vibrating nails. Gwen can also pull the string of one of her wooden figurines, attaching it to an enemy with a successful attack from her or Laurent. The target is strung for 1 minute. Until the creature is no longer strung, you gain the following benefits:

• Damage rolls Gwen makes against the strung target (including the initial attack) gain an additional 3 cold damage.
• Upon the strung target dying, Laurent gains temporary hit points equal to your artificer level + Intelligence modifier, and the wooden figurine becomes a bouquet of Winter Roses that do not wither.

You can't use this feature again until you finish a short or long rest.
