Chanters chants

[DarkWanderer]

How does phrases work (how much time)? I've watched videos from character creation and phrases didnt have any information about how long each of it works (base time - i assume its modified by INT) - i heard that phrases are overlapping so they obviously last longer than the time of chanting them, but do they last long enough that all of chants possible phrases will be stacked at once? What is the average duration of effect of one phrase - 2/5/10/20 sec? What is the max ammount of phrases stacked at once?
