race features:
Skin of the Silver Sea. Narathi are able to form a symbiotic relationship with Narathal's quecksilver-like water, giving them a highly adaptive second-skin armor. In default, this second skin adds +2 on AC and can't be destroyed, but only melted and thus made useless by its wearer. The wearer can wear armor above it. Silver Expertise. You gain one tool proficiency of your choice. 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.
