RedBuster

RedBuster (JP: レッドバスター Reddo Basutā) is a recurring ACT^{[note 1]} in Deltarune, usable against King and Queen. It is an upgraded version of Rude Buster that costs 60% TP and does significantly more damage than the standard FIGHT command, using both Kris's and Susie's turns. Susie launches a red energy wave from her axe at the targeted enemy.

Main story

Chapter 1

RedBuster is first unlocked after using Susie's Talk ACT against King.

Chapter 2

During the battle against Queen, RedBuster is available by default.

Mechanics

RedBuster's damage output is based on Attack and Magic using the following formula:^[1]^[2]

$(A t t a c k \times 13 + M a g i c \times 6 - T a r g e t D e f e n s e \times 6 + 90)$

Like Rude Buster, it deals 30 more damage if [CONFIRM] is pressed mid-attack. The TP cost is not reduced if Devilsknife is equipped.

Trivia

There is an unused spell version of RedBuster that that costs 0% TP and can be used independently from the ACT menu. It is otherwise completely identical to the used version.

Notes

↑ Although in-game references to this ACT treat it akin to a spell, internally, RedBuster is treated as an ACT.
