Skill upon being summoned?

I don't think the skill that the Ice Dragon uses when being summed is the Hail Storm that the Crystal Deer pet uses, what happens when the Ice Dragon is summoned is more along the lines of Ice Spear, while as the Crystal Deer just stuns the enemy. It makes sense, the Ice Dragon having Ice Spear, Thunder Dragon executes Thunder upon being summoned, and the Fire Dragon uses Fireball. Relativity speaking, of course.

The effect is closer to that of Frozen Blast. But yes, they are not the same summoning skill.
