Good Footing

Good Footing is a gem effect in Xenoblade Chronicles. It adds a percentage chance that the user will not be affected by blow-down. They will still take the attack's full damage.

Overview
Blow-down is a very destructive effect that by itself can turn the tide of a battle in the enemy's favour. Even one party member being able to shrug it off can make a huge difference - not only in being able to help everyone else out of the potential early, but in not wasting time being sent through the air. As many attacks deal blow-down to the entire party - most notably nebula explosions - it's probably best played on the player character to be most efficient at rescuing the others.
