Pain

Includes disabling controls or toning down the controller responses for a brief moment as the character flinches in pain. The magnitude of the effect may be relational to the damage caused or the amount of presumed pain such an attack would cause. The pain effect may last a significant period of time without being a literal injury.

Turn-based games need additional care as despite there being a clear response for being hit and all, the involved pain does not actually affect gameplay in the least.

Interrupting skill, spells and special moves is usually an additional feature. But do note that action interruption is not the only thing this should cause. This may be enough for turn-based games, although this would depend on the turn-based system implemented.

Games where a special skill or weapon with special attributes needs to be used to cause pain do NOT count.

This is generally in contrast to games where the characters get hurt and maimed yet shrug them off like nothing happened (except maybe for the screen flashing red and the character screaming).
