Strategy
Bring one or more monsters that can dispel the group and remove Continuous Damage effects.
Group healer is advised.
At wave 5, you may want to only focus on the Boss as he will counterattack any monster that destroys a Crystal Tower.
If you can manage it, kill a Crystal Tower by letting a Continuous Damage effect do final damage; in that case, the Boss will not counterattack.
Bosses and towers are immune to inability effects.
The dragon deals more damage once his HP gets lower than 30%, which is fatal for a lot of slower teams, as such it is advised to either take monsters that can apply Continuous Damage with your team to shorten the time he's under 30% or a defense buffer to reduce damage taken.
The accuracy cap on the dragon is 55%, hence everything above this is wasted.
Legendary Dragon quotes
"The Legendary Dragon takes merciless revenge on the monster that destroyed its crystal."
"Dragon fire inflicts stronger damage as Continuous Damage effects accumulate. Be Careful!"
