Lightning breath- instead of attacking with the gargantuan blue dragon, choose 4 figures within 6 sight spaces. Roll the 20-sided die for each. If it is a squad figure, if you roll a 7 or higher, the figure is destroyed. If it is a hero figure, roll the 20-sided die. If you roll a 15 or higher, the figure is destroyed. This attack may be used once per round.

Flight- Do I need to explain?

Treasure protector- The Gargantuan blue dragon must start the game adjecent to a treasure glyph. If he is adjecent to a treasure glyph, roll 1 extra defense die.

The gargantuan blue dragon cannot recieve any bonuses or penalties (either glyphs, army card powers, or from the terrain) unless the bonuses are granted by his own powers. All figures attacked by or attacking the gargantuan blue dragon cannot modify the amount of die they roll in any way.
