The official Basil icon.

Basil (バジル Bajiru?) is a special consumable herb item. The effect of using a basil results in one party member receiving an increase in their max PSY (Psyche) by 1. It can be used while moving or during combat.

In Tales of Xillia 2, it can be bought for 30000 Gald and sold for 300 Gald. It can be obtained from the Sapstrath Deepwood after clearing the game and also from the coliseum against a Dark Teagle at a 4% drop rate.
