Mage Focus Items/Effects

[Calibix]

So the Ro focus items are no drop, but I'm assuming you can turn the items in on your mage to get them. However, the quest says minimum level 33 on the wiki. Can I do this quest before then?

Furthermore, does the focus affect only give additional HP like the pet guide suggests? I have heard that it increases the level of the summoned pet by 1. Which is correct?

Thanks in advance.
