Magic Mastery Q

i got a question on Magic Mastery, the extended duration applies only to yourself right?

so wouldnt that be a bad thing, say for hs. it lasts 3min (2min + 1min) for yourself (if you're a bishop-priest) but it only lasts 2min for other ppl. harder to tell when to hs your party then right?

Not sure, but if I had to guess I'd say the whole party or else it's a pretty lol skill for Bishops.

At this point I can't keep Tespia from crashing long enough to find out, but based on the skill description and our track record, I'm gonna say lolskill.

It's a bit difficult to tell from videos because of the overabundance of HS mules and low level Bishops/Priests used in training parties, but I have not seen any evidence of Magic Mastery boosting HS's duration to more than 2 minutes for anyone but the Bishop.

Damn. That makes it a right hindrance. And it's passive, to boot...
And yet, give up 30 m.att just so I can know when to buff my party mates?
I guess I could learn to just identify 2/3 icon full.

It's annoying that you won't know when to rebuff teammates but at the same time it has the advantage of boosting whichever buffs you recieve from other classes. 1,5x duration SE, HB, etc is quite nice.
