TensionGem

The TensionGem (JP: テンションジェム) is a consumable in Deltarune that increases the party's TP by 50% within a single encounter, similar to TensionBit and TensionMax. Like other Tension items, it is unique from other consumables since TP is gained immediately upon selecting it instead of when the party's turn ends, similar to the effect of DEFENDing. The effect can be reverted by cancelling the party members' turns.

A total of three TensionGems can be obtained throughout the game, one in each Chapter from Chapter 2 onward:

• Chapter 2: One is rewarded upon clearing the "Ch2 All Stars" Challenge in Castle Town's Party Dojo.
• Chapter 3: One is rewarded by Ramb in the Green Room upon getting either an A-rank or B-rank on Board 2.
• Chapter 4: One is found in a hidden chest south of the East Belltower in the first Dark Sanctuary. The chest can be obtained by letting water push Kris down while climbing above a specific tile, where there is seemingly nothing to catch their fall.

Additional uses

In Chapter 4, Susie acknowledges any TensionGem, TensionBit, or TensionMax in Kris's inventory as "Orange hard candy" during Catty's sermon in the church, causing the AncientSweet to be unobtainable.
