Each level of each tower has 7 possible quests. What quest you get is random, but each quest has a fixed time. Higher level dragons give you a better chance of completing the quest, as does matching more of the quest elements with each dragon you send on the quest.

Each successive tower gets more difficult. The maximum possible chance decreases and you need higher level dragons to maximize the chance.
