Chosen skills/items can display an indicator above the target during their animations. The outer part of the indicator shrinks down and if the player presses the designated button when it meets the inner part of the indicator – the skill can do enhanced damage/healing or apply/remove a state.
This indicator can also be applied to actors and equipment to allow the player to defend against enemy attacks by applying/removing a state or decreasing the damage of the incoming attack.
Each skill/item/equip/actor can use a different indicator graphic, be different speeds and have different difficulty of their timed presses. They can also do different state and damage modification.
Vocab can also be set up to display different text in battle log when a timed hit is successful.
