Tension Swing

Tension Swing is a gem effect in Xenoblade Chronicles and Future Connected. It reduces the amount of required to change between tension states. This is similar to, but not necessarily the same as, increasing the amount of tension gained and lost from all sources.

Overview
Tension Swing can be risky because it works both ways, making it easier to fall into low tension just as much as it helps to get into high tension. Since it is relatively easy to encourage away low tension, it is probably a benefit overall. Characters that make best use of tension are (for Happy Happy), Seven (for Final Cross), and  (for maintaining Elemental Burst ).
