Whenever any player is dying, you may discard a red card from your hand to use it as a Peach, restoring 1 HP to that player (yourself included) and saving them.
Once during your play phase, discard a hand card to restore 1 HP to any living character — yourself or another — a steady second lifeline on top of your dying-rescue heal.
Hua Tuo is the table's lifeline: he can spend any red card as a Peach to pull a dying player back from the brink — himself included — so he sustains the board almost endlessly. He shines as a Loyalist propping up the Lord, or as the Lord himself thanks to deep self-healing on 4 HP. His weakness is offense: with no attacking skill he relies on others to close games, and enemies make him their first target once they see he keeps everyone alive.
