For the bottom actions of these cards, the light part is what is applied to the ally as a persistent bonus. This card is technically owned by the ally now, and they can recover it through special actions like any other card they own. These cards should be returned to the Sawbones at the end of the scenario.

Using this card allows you to refresh one consumed or one spent item you have equipped.

If the target is poisoned, will this ability heal the target 3 damage and remove the poison or only remove the poison and not heal the target?

The poison gets removed, no other healing happens and if you have any other negative conditions, they get removed too.

For the top action, this card is put in the Sawbones' discard pile at the end of the round. The Sawbones' ally never technically owns the card.

The bottom effect applies to allies only while they are adjacent to you (like an aura), not allies adjacent to you at the time this action was performed.

These cards have an X (R1) / M (R2) on them, but they are not cards that are included in the Sawbones' normal hand. Instead, keep the stack of them off to the side and hand them out to other characters when an ability tells you to. When these cards are lost, or the scenario ends, return them to the Sawbones' supply.

Unless the range is otherwise stated, all moves and attacks can become heals with a range of 1 (affect yourself or an adjacent ally).
