• Hold the key: the spear drawn far back, flames at its point, you are slowed while you charge (1.5 seconds for a full charge). Nothing is spent until you let go.
• Let go: you thrust, and a beam of Qi leaves the point straight ahead: 5 blocks uncharged, up to 8 blocks fully charged, 1 block wide.
• It goes through everyone in its line (×1.5 each) and pushes them back; a wall or any solid block stops it.
• The ground is ploughed along the whole beam.
• Held more than about 3.5 seconds, or with the spear out of your hand, the charge is lost.
• Under 20 % of your health, it is the secret Breaking the Cauldrons.
