Moore the Merrier is a limited-time Lunar New Year unit, a Wind mage that works like a support damage dealer since she can inflict some status effects (poison, sleep, or silence), as well as some debuffs if the status effect lands.
With the theme of Longevity and Prosperity, she comes with some self sustain in the form of HP and AP regen moves, plus an upgraded reraise that gives her some damage increase as long as the reraise effect is available. These moves also have multiple use limits, which can be quite useful in drawn-out guild battles. Having access to Quicken from Time Mage sub-job also means that she can potentially be relevant for a long time since she can default to a full Quicken support bot, even if her damage falls in the future.
Meta unit against evade her accuracy is amazing! And Status procs is fun...
poison sleep and silence!!
Sadly she can't hurts celes but anyway maybe with rune knight sub job? Well i don't think she is good against celes but with meta evasión is really powerfull.
