Spirit Chicken is so good this season, the best chicken build ever. Unfortunately the build doesn’t work without the season bonus. You need Wormwood, Barber and Gazing Demise in the cube.
Most definitely … they need to add this Seasonal theme back into Non-Season … there is no reason to limit Cube choices … it just closes the door on build variety and creativity.
I was running a variation w/o Wormwood in the cube that worked out great for both SP GRs, bounties, and NRs (with some swaps depending on situation):
