Thats not a Dragon with a passive. It has to be another sentence stating that is has the ruler of dragon
The 4-day dragon was always giving you the passive as it was "mighty".
If you don't get the passive they either changed the dragon you get or it is indeed a bug.
Ive used the mighty armored dragon from the event, and I didn't get the passive skill i should have [ ruler of dragon ]
did anyone notice it either?
same here ...
Yes... it's bugged after the newest patch...

I got a reply from tera support and they said that this is intended behavior :
"When it comes to the issue with passive skill from the item "Dragon Skill: Mighty Armored Dragon (4 Days)", please be aware that this is working as intended, as the temporary Dragon skill is not giving the passive skill."

Omg how is this an intended behaviour? It was always like that, giving the passive. 
Even the tooltip says so.
sigh
@Athena Tomorrow's maintenance description doesn't mention anything about the fixes on the Ruler of dragons bug... When is this supposed to be fixed???
i wanna know too 
Why would they fix it ,if it's not a bug but "intended behavior"...

they know ....
Hello,
The 4 Days dragon passive works again! 
Yes this is intended, you can only get a temporary passive if you have no permanent one of the same power (only 1 x 1.5 and 1 x 2.0).
I like it, no pentadragon anymore (perma 1.5, 3 day 1.5, 7 day 1.5, perma 2.0, temp 2.0).
