Louelle

Louelle is an earth element magic damage dealer that can cast pretty fast. She has high MAG and 3 different offensive mage jobs that can make her effective in certain situations. Scholar sub job can be potentially deadly against bosses or pvp, Rune Knight makes her a strong Lightning element killer, while Black Mage sub job comes with non elemental spells that can be used on most enemies.

Compared to Black Mages, her Scholar main job has a lot of strengths which starts from the passive, Knowledge Reserves, lowering the activation time for all of her spells, and makes one of her highest attack damage spell, Devitalizing Glint, into an instant attack. She can further decrease casting time if you use Law of Speedreading from Scholar sub job, and even more if you use VCs like Envious Magician or Becoming Stronger Than Anyone Else. She also has 2 nice defensive buffs (Law of Preservation + Earthen Calling) that can make her surprisingly tanky, then Drain Evocation for some self sustain.

Her Rune Knight sub job comes with more non-casting damage abilities, but at a shorter range. Stonega Blade deals high damage, and is effective against Lightning enemies. Black Mage sub job are all low AP damage spells with no side effects. Some of them are elementless, which can be good if you want to use her against Wind enemies.

Her EX upgrade can potentially be a game changer, at least until 22. Job level 19 increases the ATK value of Earthen Calling and makes it into a non casting ability. At 22, Magic Orb becomes an instant ability that can reduce enemy's AP.
