In this image, skill icon is denoted by the number 10

Skill icons (スキルアイコン sukiru aikon) are common abilities that nearly all units have based on their grade. Each icon shows which ability the unit has.

There are currently four types of skill icons: Sk boost Boost, Sk intercept Intercept, Sk twindrive Twin Drive!!, and Sk tripledrive Triple Drive!!!.

Some card abilities can cause units to gain or lose skill icons. As skill icons are not inherently tied to a unit's grade, abilities that alter the grade of a unit will not affect its skill icon.

Sk boost Boost


  • At the same time as you are choosing the attacking unit and your opponent's unit to be attacked for a battle, you can also choose a unit with "Boost" in your back row of the same column as the attacking unit, and [Rest] it to boost the attacking unit. The power of the boosted unit increases by the power of the boosting unit until end of that battle.
  • If your vanguard is in Legion, you choose one of the two vanguards to be boosted.
  • The power of the boosting unit is continuously added to the boosted unit for the duration of the battle. If the boosting unit gains further power at any time, the new amount of gained power is also added to the boosted unit's power. If the boosting unit leaves the field or loses its status as boosting unit, the boosting power disappears as well.
  • Currently only grade 0 and grade 1 units have "Boost".
    • The exception to this is Takugal (grade 3) and Eternal Wing (grade 4), both of which are illegal.

Sk intercept Intercept


  • During your opponent's guard step, if your rear-guard with "Intercept" is in the front row, is not being attacked, and another of your units is being attacked, you can move the card with "Intercept" to your guardian circle.
  • This is considered moving the unit from rear-guard circle to guardian circle (as opposed to placing it on the guardian circle), so "When this unit is placed on (GC)..." abilities do not activate.
  • The units that have intercepted become treated as guardians in the guardian circle, and will retire once the battle ends regardless of whether or not the attack hits.
  • Currently only grade 2 and certain grade 1 units have "Intercept".
  • Certain effects allow to your units to intercept from the back row.

Sk twindrive Twin Drive!!

Japanese:「ツインドライブ!!」(Tsuin Doraibu!!)

  • It gives the unit with "Twin Drive!!" drive+1, allowing them to drive check two cards instead of one during the drive step.
  • Currently only grade 3 cards and grade 4 normal units have "Twin Drive!!".

Sk tripledrive Triple Drive!!!

Japanese:「トリプルドライブ!!!」(Toripuru Doraibu!!!)

  • It gives the unit with "Triple Drive!!" drive+2, allowing them to drive check three cards instead of one during the drive step.
  • Currently only grade 4 Stride have "Triple Drive!!!".


  • G guardians are the only units to lack skill icons.
  • In the anime, units with abilities that grant them extra [Shield] upon intercepting are called "Especial Intercept".
