paralyzing is a general effect. If a striker hitting a pressure point is considered paralysis in the same way a mage casting 'stun enemy' is paralysis. The difference is the striker/monk is using a physical part of the body to do so, and the caster is using magic. Snares, and traps are a generalist rogue thing. And Movement Impairment is general. A person casting a freeze spell on your leg is movement impairment in the same way getting poisoned and being sluggish afterward is.
