If you have multiple wizards, you can work on leveling a pet on each wizard every 8 hours. I switch from one to the next, until all pet energy is drained, and then go farming. Also, every time your wizard levels, it refills the pet energy. So if I know that I am going to level, I will go spend whatever pet energy I have, and then turn in the quest to level up. Then I go spend that pet energy, and wait yet again. I have leveled my Firezilla to Ancient today by using this technique.
