There is a site with the info. Print it out - dragoncity.wikia.com/wiki/Attacks It shows the dragons, their highest attacks and point damage. They list Legend and Crystal can have Legend Spell attack with a max. of 17373 damage points. (Remember the points are raised by the level and stars the dragon has.)
