Tension Bit is an item found in the Cyber Field. It increases the team's TP by 32% within an encounter. Malius can fuse this item with B.ShotBowtie to make the Tension Bow. Its upgrade is the Tension Gem, an almost identical item that grants a 50% TP increase instead of the 32% of the Tension Bit.
- (You felt tense.) (... try using it in battle.) [When using it outside of an encounter]
- Tension Bit is the only item in Deltarune that can be changed through any means to be a different item type at present (Tension Bit, a battle item, can be fused into a Tension Bow, an armor).
- Tension Bit, Tension Gem, and the (unused) Tension Max are unique from other consumable items. TP is gained immediately upon selecting it instead of when the party's turn ends. The effect can be reverted by cancelling the party members' turns.
