Oh let's see... back before Lupa broke the lv75 limit we were helping her skill up parry. We camped down in the Boyhada Tree and pulled the black mandies down in there. She would tank them while Uloulo and I spammed buffs and cures on her. Uloulo's Animus spells (Minuo on him and I and Augeo on her) were awesome for keeping hate on her during this project.
She nearly reached the lv75 cap doing this and it was before the skill up rate adjustment made to Parry. Uloulo and I made good progress during that time as well. Both of us capped Enhancing Magic with buff spamming, using spells like the Animus ones, Haste, Regen, and Storms while farming gold chests in Abyssea.
The biggest thing with Enhancing Magic is pick out spells that have the shortest duration and then reapply them as soon as they are down. If you are using haste to do this, your party will love you. lol
