Spiral Treptune T4, known as Screw Trident (スクリュートライデント, Sukuryū Toraidento) is an Energy Layer released as part of the Burst System as well as the God Layer System. It debuted with the release of the BG-08 Random Layer Collection Vol. 8 in December 2017 and was later released as a Booster in Japan on February 17th, 2018.


Spiral Treptune T4 is a Stamina Type Energy Layer with trident motifs meant to represent its Japanese namesake; Trishula, a three pronged spear in Hinduism. Like its predecessor Treptune, Spiral Treptune T4 features three large blades to create an overall triangular shape. As part of the God/SwitchStrike Layer System, Spiral Treptune T4 features gimmicks; the center and blades of the Layer are connected by rubber to create “Bound Defense”, akin to Jerk.

In theory, the rubber would allow the blades would shift under impact and absorb shock to reduce recoil. In practice however, due to how hard the rubber is, the gimmick fails to function. This issue is exacerbated by the triangular shape of the Layer which creates high recoil and Burst Risk which the four medium teeth of the Japanese release are unable to compensate for.

Despite the high Burst risk however, Spiral Treptune T4 performs well in pure Stamina combinations as its weight distribution creates spin times near or equal to Caynox C3, albeit without Destabilization potential.


Despite the recoil, ineffective gimmick and high Burst risk, Screw Trident’s high Stamina makes for an excellent alternative to Deep Chaos if the latter is unavailable.

As such, Screw Trident is a must have for bladers if one does not have Deep Chaos and a welcome addition if one does.
