Meira

Unique Spider Girl. Meira can be seen in the market as the miracle healer on the first 3 days (excluding day 0) of the game and then subsequently every 10th day. She offers to join your team after she heals 5 units, so you need to suffer 5 injuries and pay 500 gold. Needless to say, if you chose death as a result of defeat at the start of the game, you won't be able to recruit her.

While Meira is a very good support unit, she also has the potential to be a strong frontline fighter. The combination of her jump movement, Agile and Precision gives her the mobility to get into position where she can utilize multi hit weapons like spears and broadswords to maximize damage while not injuring allies.

Her unique skill HealingWeb also lets her heal and remove injuries outside combat on the Overworld, as well as remove injuries at home through her character screen. Her Mending trait is also quite rare.

Can't be changed with gender potions.

Produces HealingSilk.

Also she is a mercenary, costing you 150g per day

The Healing Silk you get can be sold for a 100g per day, which would cover most of the extra cost by itself, though, frankly, selling it would be a waste of rsources.

And she's quite capable of covering her own hiring costs in a brothel (but keep an eye on her stamina reserve, since she'll need it to treat injuries).

She's also a genetic max level 15 character that you can grab right on day zero (just go get injured on purpose in a training fight) and that's worth a lot in itself.
