How do breed auras and the Center placement work in Dragonfire?

Every breed carries an aura that spreads from where it stands. The Center is the hub: a dragon there covers the whole line with its aura.

Values seen in combat:

• Champion: *Ebbing Fury* (−27.5% enemy damage), *Champion's Brilliance* (+15 Strength/Intelligence/Instinct) — the strongest on average.
• Warrior: *Battle Rush* (+25% Initiative to allies) — excellent for striking first.
• Sentinel: *Wise Vigor* (+20% Instinct, plus Recovery).
• Hunter: *Blazing Onslaught* (a debuff: +10% physical / +15% fire damage taken by the enemy).

The rule: put the dragon whose aura is most worth spreading at the Center — usually a Champion (−27.5% enemy damage is enormous), or a Warrior if you want to lock down Initiative.
