Poultice is a character deck card in Back 4 Blood. It is a Discipline Type Card with Defense 
Affinity and is great for extra healing in many healer-deck builds.
Card Ability
When you use a Medical Accessory, the target heals for an additional 20 Health over 30 seconds.
Poultice gives an effective 20 extra Health on top of any Medical Accessory use as long as you or your teammate can survive during its 30-second healing over time.
Unlike other healing abilities, Poultice is not affected by +Healing Efficiency.
Pros
- Activates with all Medical Accessories, including Pain Meds
Cons
- Heal over time ability instead of an instant heal
- Does not heal Trauma Damage
- Can be considered non-essential over other healer builds cards
Card Synergies
Poultice is best used in healer decks since it heals teammates and gets buffed with cards that increase +Healing Efficiency.
Group Therapy – Like Poultice, Group Therapy also activates when using a Medical Accessory except that it heals the whole team.
Field Surgeon – Gives an added benefit to Poultice by also healing 3 Trauma to the target when you use a Medical Accessory.
Medical Expert – Also heals 1 Trauma to the target when you use a Medical Accessory.
Pain Meds Enhancers
Players can also take advantage of the 2 Pain Meds enhancement cards to further give the player bonuses when they use Pain Meds to trigger Group Therapy in Back 4 Blood.
Stimulants – Gives the player 10% Move Speed, Reload Speed, and Weapon Speed for 30 seconds.
Chemical Courage – A purely offensive card that increases damage by 25% for 60 seconds. Great for using just before boss encounters. Heal up and add to your firepower.
