  • Ostia's Pulse's cooldown count changing effect will not trigger if the unit is inflicted with  False Start.
  • Cooldown count changes from skills that activate at the same time as Ostia's Pulse (at start of turn) are not considered in Ostia's Pulse's conditions.[1] Skills such as Infantry Pulse 3.png Infantry Pulse 3, Icon Class Green Tome.png Tome of Reglay, and Odd Pulse Tie 3.png Odd Pulse Tie 3 will have their effects stack.
  • The stat increase that can be applied by Ostia's Pulse II is considered a  bonus.
    • Any 【Bonus】 on a unit, including  bonuses, lasts until the start of that unit's next phase. If  bonuses are acquired during the enemy phase, they will disappear when the next player phase begins.
  • Movement Types refers to if a unit is:  Infantry,  Armored,  Cavalry, or  Flying.
  • In order for the skill to trigger with an ally unit, the team must have fewer than 3 allies sharing a movement type on the field.
  • Ostia's Pulse takes account of ally units on the field at the start of the phase, meaning if allies are lost it is possible to meet Ostia's Pulse's condition and trigger the skill.
    • Example: A team consists of 1 Armored unit with Ostia's Pulse & 3 Fliers. The skill cannot trigger with the 3 Fliers because there are more than 2 of them on the field. Should the third flier be defeated, Ostia's Pulse's condition will be met and the skill will trigger.
