Healer's kit

A Healer's Kit is an item that allows a creature to cure wounds and heal poisons and diseases. It is used in conjunction with the Heal skill. The Healer's Kit's power (+1 to +12) is added to the skill roll.

BoW notes
On BoW, Healer's Kits are given to characters as rewards. Each member of the team that wins a round receives a Healer's Kit +10. Each member of the team that wins Capture Point receives Healer's Kit +1, +3, +6 or +10. Healer's Kit +12 are sometimes as given as gifts by the Keeper of War to guild members.

Healer's Kits are the only item that may be transfered to another character without twinking. They may be given to teammates by placing them in the bin in your team base.
