On my main, the character I first got to max level and tend to always try new content first (as opposed to my other 8 max level characters), I got to a point where I have one level of ascension left to max all 4 out but have no more celestial ascensions or overloaded ascension potions left, due to using them on the pre 110 levels foolishly, so I have been just waiting for it to regen normally to finish out the level and trying some of the weekly quests to see if I can get lucky on a celestial ascension drop. Something strange happened today. I had done the weekly outdoor solo mission and finished level 12 Geomancer then used my last celestial ascension to get me to level 14 and my ascension exp was 0 or very low. I decided to work on the new TS timeline and when I had completed the first mission I noticed my guided ascension exp bart was maxed. The question I have is: Does doing the TS mission refill your guided exp? At first I thought it might be the orb of concentrated memories, I had used it the day before on the TS quest when my TS vitality hit 0 hoping it would refill it (unfortunately not), but I tested that on another character and the guided exp didn't refill so the only other thing I know I did was the first Stitch in Time mission. Anyone else see this?
The Hammer of Adept Hands from the Loyalty Merchant is what refills your TS vitality. As for the other issue, I have no Ascension classes maxed and tend to ignore them.
