When opening up the Chanter UI for my Chanter (lvl 6, INT 17) I noticed for all level one chants:
Duration 4.0 sec.
Linger 2.7 sec.
Aura: .... for 8.1 sec.
Now:
I might not be getting something, but from my understanding 4.0 + 2.7 should be 6.7, not 8.1 I thought (Wiki, forum posts) the INT bonus is not applied to linger duration. Was that changed? Not that I mind, 0.7 seconds is really not that much but it makes the investment into INT feel more worth while.
I noticed the above also for newly (i.e. post patch) created Chanters. For INT 10 duration is 4, linger is 2 and (what I assume is) the total as expected as 6.0.
