Aira

One of the game’s only sustain warriors, Aira is capable of dealing tons of damage while being extremely tanky. Her use in the early game is especially useful if you do not have the resources to funnel into both a tank and DPS, since she can technically fulfill both roles.

  M1 changes effect depending on her HP, healing her when she’s low to ensure durability while dealing additional damage if she is healthy. Ideally, you want to maintain her health high to ensure S1 procs, where she can deal additional damage based on her own max HP, and this is easily achieved with healer support and her innate regeneration whenever she falls low. Her S3 is also a useful debuff that reduces all DEF, Physical and Magic resistance for 10 seconds, useful for softening the enemy frontline.

Her use starts to heavily decline as you approach the later chapters, since she is not durable enough to be a pure tank, and doesn’t deliver as much damage as a backline.

Even a hyper-invested Aira would not be enough to be as tanky as a pure tank like Chloe or Claire, nor deal as much damage as a pure DPS like Mephi or Vivi. She might see some use if her artifact achieves the highest level, where it completely stops enemy units within her range from recovering mana, but this will be extremely end-game which we have not reached yet.

Single Bosses

Aira is an excellent frontline due to her S3 reducing DEF, physical and magical resistance by up to 24%. Her single target DPS is also commendable when she is above her threshold for her S1 and M1 to activate the bonus damage, and the stun is also much needed if we see similar mechanics in the future.

PVP

Aira acts as a pretty decent frontline but is less durable compared to Chloe or Claire. Since there is a lack of defensive subs in exchange for offensive subs, she could be easily bursted down by focus fire. As such, you will rarely run into her until the beast faction as a whole gets better units (see Honglan)
