Mage solo strategy question

[thecrazedgoblin1]

Hey all. I read the various magician guides and was wondering when I should start using fire pet and killing it once mob is low enough to finish with a single nuke? Im lvl 8 at the moment and it doesn't seem very mana efficent at this level. Is the fire pet focus item a prerequisite for this? If so any chance someone would be willing to help me get it if its needed? Thanks for your time.
