Accelerates Special Trigger (cooldown count-1). At start of turn, inflicts Spd/Res-6 on nearest foes within 5 spaces of unit trough their next action, if [Bonus] is active on unit or [Penalty] is active on foe, inflicts Spd/Res-6 on foe during combat, and also, the following effects will occur base on the value of total bonuses on unit + value of total penalties on foe: if ≥ 6, "neutralizes effects that prevent unit's follow-up attacks," and if ≥ 18, "foe cannot counterattack." (Example: if unit has +6 bonus to Atk/Spd and foe has an -6 penalty to Atk/Spd, the calculated total will be 24.)

[Bonus] All effects that last "for 1 turn" or "that turn only." includes bonuses that granted by a skill like rally or hone and positive status effects (extra movement or effects like Dominance)

[Penalty] All effects that last "on foe trough its next action." includes penalties inflicted by a skill like Panic or Threatened and negative status effects (preventing counterattacks, restricting movement, or the effects of a skill like Triangle Adept or Guard).
