Slow (gem)

Slow is a gem effect in Xenoblade Chronicles and Future Connected. It grants a percentage chance that the user's will inflict  on the target for 10 seconds. The strength of the effect is hardcoded as 50%.

Overview
Slow is a decent debuff to inflict, making the target foe eventually lose auto-attacks and thus speed of access to its Talent Art(s). It is only decent though, and is unlikely to majorly help turn a fight around.
