Variations
The version of the track used in the above instances (and in the Xenoblade Chronicles 2 Sound Selection) differs slightly from the version featured on the Xenoblade2 Original Soundtrack (and the version showcased before the game's release as 'Action Battle'). Specifically, the version used in the above has slightly different orchestral balancing, most noticeably including much more prominent strings and less prominent electric guitar at 0:39.

The version featured on the Xenoblade2 Original Soundtrack also plays in-game, when T-elos uses U-TENERITAS on the Indoline warrior monks during her Blade Quest Lingering Resentment.

A third variation of this track, which lasts much shorter and has a significantly more prominent drum line, plays in the following cutscenes:
 * Sheba enacts her Divine Punishment upon the Nopon that swindled her in her quest, Fool's Gold.
 * Zenobia launches the Thanatobeast Andraz in her quest, A Real Challenge.
