I would say it has no holes, but has a thin covering over everything. It resists endurance drain and slows somewhat, has toxic/smashing/lethal resist but not def, and defense to energy/elemental but not resist. It even has some psi def to work from so it isn’t totally open to psi damage or terrorize/confuse. It also has healing/absorb and endurance recovery. Everything but bio has a hole with at one of those things.
