Some gameplay tips:

To max the fire skills, tt is recommended to first Max Fire Mastery. Then Fireball, Firebolt and Inferno.

Many people say that Inferno doesn't directly add Meteor's damage. So it's not worth to be Max'ed. In fact, Inferno will increase the duration and damage of the fire after Meteor falls onto the ground. So it is very useful especially when you are killing Boss level monsters.
