Askari

Hardened Against Magic. You can use this feature to advantage when making a saving throw against a magical effect. You can use this once before you must complete a short or long rest.
Relentless Endurance. When you are reduced to 0 hit points but not killed outright, you can drop to 1 hit point instead. You can't use this feature again until you finish a long rest.
Savage Attacks. When you score a critical hit with a melee weapon attack, you can roll one of the weapon's damage dice one additional time and add it to the extra damage of the critical hit.
Born of The Sands. You’re naturally adapted to hot climates. In addition you can go for twice as long without water, before being exhausted from dehydration.

Languages. You can speak, read, and write Common and Madan. Madan was the language of their former masters, though the Askari have a much rougher pronounciation of it. It uses a unique alphabet, written in dots and lines.
