How many heroic acts a single character can perform in a battle?

[BaronZen]

Hello, i wa s studyng the game basics and rules but this is not clear or better: i understood every character can perform 1 heroic for fight and that momentum bar is shared between all six, so my question is: since with leveling and adding the second archtype you can get another heroic skill (even some psyker staff have them like sanctic emperor wrath), the limit is always one for fight or is it one of every one heroic you can do? Example can i do in a fight with an sanctic officer strategist the sanctic staff heroic, the officer heroic and the strategist heroic or only of them?

By default only one heroic per character per fight, so only of them. Though some of the heroic act upgrade can bypass this limitation
