The official Hourglass icon.

Hourglass (アウワーグラス / 砂時計 Auwāgurasu / Sunadokei?) is a unique and special consumable item. The effect of using an hourglass is that it is able to stop enemies for a fixed period of time. The fixed period of time can then deliberately be used to continuously attack enemies, recover health or technical points.

In Tales of Xillia 2, the hourglass cannot be purchased but can be sold for 3000 Gald. It can be obtained after clearing the game as a special item and also after defeating Chronos (3) at a 100% drop rate. The game mentions that the hourglass is similar to the Chromatus in notion, as they allow a character to use time to their advantage of attacking an enemy.
