Mage Focus items questions:
 

1) Are all of them worth doing or do I only need one or two of them?

2) What do they do? I keep getting so many opinions like only more health, or makes pets a higher level, etc

3) Can you do them at like level 1 with no faction work?

1) You need a few of them for epic if you plan on attempting that \o/

2) they increase the pets health and size, from old websites and wiki stuffs its supposedly (while using a focus)

fire pet's hp = air pet, air pet's hp = water, water pet's hp = earth, earth's pet = banana?

3) can do at level 1 just need the items, but I believe you need to be level 5+ to leave the newbie zones now?

1) The most important focus item you need as a magician is the torch because fire pet is golden for solo xp. Also, the reclaim energy part is nice (All focus items have this reclaim energy clicky). Till 49, I would recommend water pet in an xp group due to its DD proc, so stein would be a 2nd good choice. Last but not least, Shovel and Broom are required for magician epic quest, so you might want to do them, though those could be low priority.

2) They both increase HP and level of your pet. A max pet focused has 1 more level than a max pet unfocused.

3) Yes you can
