I want to know whether this is balanced compared to the other race options. If not, what can be changed?
Necrolyte
A race of Humans transformed into semi-undead beings long ago by their own profane rituals. They combine Spells with Armor to great effect.

Age: Necrolytes reach maturity as 20, but can live as long as 1000 years of age.
Alignment: Necrolyte society holds pragmatism over law or chaos, with no sympathy or mercy shown towards Non-Necrolytes. As such, they are typically Neutral Evil.

Necrolyte Magic: You know the Inflict Wounds spell, and can cast it once per short or long rest. When you reach 3rd level you learn the Blindness/Deafness spell, and can cast it once per short or long rest.
