Mage,as we know, does not generate as much rage as warrior, and apart from very rare dragon dive only casts mana acc., lightning ball + treasure. Now how many levels of pet dragon do you need to max out these 3 skills? 30 max.

I totally argree with the skill use. Alas, to max them out can take a long time if the 3 upgrade choices per level are all for different skills. A lot of dragon levels are "lost" to upgrading Lava Call and Stone Wall.
