The Vortex Finish (ボルテックフィニッシュ) is Kamen Rider Build's set of finishers. Each Full Bottle set has a variety of different finishers.

Build
After turning the crank of his Build Driver after transforming into any particular Best Match or Trial Form, Build can activate a finisher tied to those two Full Bottles. Best Match=
 * RabbitTank: Build dives underground to send a white energy chart flying up to the surface with the dotted line securing the enemy before leaping back up, and delivering a kick whilst riding the chart's line. According to Blood Stalk, this finisher has a Hazard Level of 3.2, and then 3.7 when Build attacks him out of anger.

Cross-Z
After turning the crank of his Build Driver after transforming, Cross-Z can activate the Dragonic Finish (ドラゴニックフィニッシュ). This attack has two variations:
 * Rider Kick: Cross-Z summons a blue and orange energy chinese dragon that flies behind him, then jumps up as the dragon breaths fire, sending him at the enemy, then delivers a roundhouse kick whilst his foot is covered in blue energy.
 * Rider Punch: Cross-Z coats his right hand in energy in the shape of a blue chinese dragon head, then delivers a punch.

Drill Crusher
The Drill Crusher's finisher is the Vortex Break (ボルテックブレイク), activated by plugging a Fullbottle into the Full Bottle Slot of the weapon.
 * Blade: Build channels the energy of a Full Bottle in his Drill Crusher and performs a powerful slash.
 * Organic:
 * Rabbit: The Drill Spiral Blade spins such that it creates a tornado before Build performs a red energy slash.
 * Ninjya: Purple energy Drill Spiral Blades are projected and spin violently around the Drill Crusher.
 * Kaizoku: The Drill Spiral Blade spins such that it creates an energy whirlpool before Build performs a double azure energy slash.
 * Inorganic:
 * Rocket: The Drill Crusher charges at the enemy and attacks like a rocket.
 * Gun: Build channels the energy of a Fullbottle and performs a powerful blast.
 * Harinezumi: Build shoots white energy spikes at the enemy.

Hawk Gatlinger
The Hawk Gatlinger's finisher is the Full Bullet (フルバレット), activated by spinning the Revol-Magazine ten times. It surrounds itself and the wielder with a white energy spherical graph, trapping all enemies in mid-air before firing upon them all.

4Koma Ninpoutou
The 4Koma Ninpoutou has four different finishers, depending on how many times the Vortex Trigger is pulled; the panels light up in ascending order.
 * Clone Jutsu (分身の術): Build creates a number of clones of himself that attack together.
 * Fire Jutsu (火遁の術): Build delivers a flaming slash attack. While performing this attack, the 4 Koma Ninpoutou announces Blazing Slash (火炎斬り).
 * Wind Jutsu (風遁の術): Build creates a tornado around the blade. While performing this attack, the 4 Koma Ninpoutou announces Tornado Slash (竜巻斬り).
 * Stealth Jutsu (隠れ身の術): Build teleports a short distance away in a puff of smoke. While performing this attack, the 4Koma Ninpoutou announces Doron (ドロン), with a heavy drumbeat when he disappears and reappears.

Kaizoku Hassyar
The Kaizoku Hassyar's finisher is the Kaizoku Densha (海賊電車). It is charged by pulling back the Build Arrow and holding it before letting go. While performing this finisher, the Kaizoku Hassyar announces Hassha (発射).
 * Build fires a green and azure energy train from the Kaizoku Hassyar that not only rams into the enemy, but shoots azure energy discs as well.

Beat Closer
The Beat Closer has three different Hit-Parade (ヒッパレー) finishers depending on how many times the Grip End Starter is pulled after inserting a Fullbottle.
 * Smash Slash (スマッシュスラッシュ): Cross-Z channels the energy of a Fullbottle in his Beat Closer, pulls the handle one time and performs a powerful slash.
 * Million Slash (ミリオンスラッシュ): Cross-Z channels the energy of a Fullbottle in his Beat Closer, pulls the handle two times and performs a powerful slash.
 * Lock: Cross-Z sends a dark blue fire stream at the enemy.
 * Mega Slash (メガスラッシュ): Cross-Z channels the energy of a Fullbottle in his Beat Closer, pulls the handle three times and performs a powerful slash.
 * Lock: Cross-Z strikes the enemy with the Beat Closer as it projects an energy version of the Bind Master Key.

Combinations

 * Build (in his OctopusLight Form) and Cross-Z perform a combination of Build's Vortex Finish and Cross-Z's Mega Slash (with the Lock Fullbottle) to defeat Blood Stalk.
