"If unit initiates combat" means if the user starts combat during the player phase. The unit does not need to deal damage, nor be the first to attack.
- However, if the effect is applied after combat, the unit must also survive it to fulfill this condition.
The stat increase that can be applied by Sly Mirror is considered a temporary buff.
As a general rule, if a unit is both prevented from making, and guaranteed to make a follow-up attack, the effects cancel out, and the Spd difference decides instead (including effects that alter the Spd difference such as Frozen).
A foe with effects such as Phys. Null Follow or Null Follow-Up will neutralize the guaranteed follow-up attack granted by Sly Mirror.

The damage boosting effect is a flat +5 damage that ignores the foe's Def or Res when calculating the damage boost, and can be reduced by damage reduction effects such as Gust, Atk/Spd Excel, and Dodge.
- A foe equipped with Embla's Ward, Múspellflame, Niðavellir Axiom, Gold Perfection, or Nine-Realm Pact will neutralize all sources of damage except from Røkkr area-of-effect Specials and the minimum 1 damage from Umbra Burst weapons.
- For more information, see Damage calculation.
The +5 damage boost of Sly Mirror will activate if the user receives a 【Bonus】.
- The +5 damage boost will not be negated if the unit receives a 【Penalty】.
- If the unit does not receive a 【Bonus】, or has their 【Bonus】 removed by a source of positive status effect neutralization, the +5 damage boost will be negated.
- For more information, see Status effects.
The +5 damage boost of Sly Mirror will activate if the foe receives a 【Penalty】.
- The +5 damage boost will not be negated if the foe receives a 【Bonus】.
- If the foe does not receive a 【Penalty】, or has their 【Penalty】 removed by a source of negative status effect neutralization, the +5 damage boost will be negated.
