Daze Tension

Daze Tension is a gem effect in Xenoblade Chronicles. It increases tension an extra amount for each hit on a dazed enemy.

Overview
If dazing is a large part of the player's strategy, Daze Tension is a solid gem to put on any character in the party. The best ones are probably those that have tension-restricted arts, specifically Riki, Seven, and to an extent Melia.

If the player is not focused on dazing, the gem is much less useful, and indeed does nothing at all if there are no daze arts in the party.
