Will they poof at end of season like the ethereal items did, or will they be available to us on our non-seasonal chars? Trying to determine if I should save any, or just use all for augments.

When will they poof? Is it right when season ends, or when new season begins? Wondering if I should use them all up for augments on my seasonal gear, or if I will have a chance to do augments with them on my non-seasonal.

they will poof when season ends. Probably around mid-summer, roughly. You will first get the PTR announcement, then 2 ish weeks of PTR, then a week or two, then season ends. Roughly a month ahead of time, more or less. Blizzard tends to announce the season end date at the very last few 1-3 weeks.

At the season end you should either salvage all of them or augment.

You will NOT have a chance to use them on non-seasonal, 100% I guarantee you that.

thanks. now i just need more regular gems to do more augments. they have been the bottleneck. got tons of shards stuff.
