The "Keep in mind, if you switch skills you'll lose your super speed." warning is most ominous, but the meaning isn't entirely clear to me.
If you switch, does it throw away all or some percentage of the time you've "bought" at the shrines? I accidentally temporarily switched skills a while ago and panicked because I thought it might chuck out 15 or so hours of purchased learning, but it seemed to save all my progress.
The skill I switched to wasn't in super speed mode, of course, but switching back to the original one restored the speed and (I thiiiiiink) the proper amount of time remaining.
If this is how it's supposed to work, then while you're learning a long skill and getting dangerously close to getting emblems with other giants, you should be able to switch to another skill, pour your 999 points into that second long skill, then switch back to the original skill without penalty.
If I understand correctly, the paused skill time will still be lengthened when you finish the original skill, but the time poured into it would not be lost.
Is this accurate?
I'm not anxious to test with half an Earth day's worth of shrine time...
