Paralysis (gem)

Paralysis is a gem effect in Xenoblade Chronicles and Future Connected. It grants a percentage chance that the user's will inflict  for 10 seconds. The strength of the effect is hardcoded as 75%.

Overview
Paralysis is a great debuff for reducing the amount of background damage the tank has to soak up, while also making it harder for enemies to get their talent arts off. That said, it's probably best-placed on an attacker, to maximize the number of chances it gets to trigger.
