I pulled Jalter!!!!
What made this even more shocking that this was only the first 30 Saint Quartz I used of the 192 I had, and I got her on the 5th summon! I thought pulling Francis Drake out of a single summoning ticket a few weeks ago was my luckiest moment in Fate/Grand Order, but this one definitely takes the cake for my luckiest and best Fate/GO moment thus far.
I also had several friends who encouraged me to use my Saint Quartz on the spot to see my reactions whether or not I would pull Jalter with the Saint Quartz I had. You can imagine how they and I reacted the moment the Avenger card appeared!
Since I managed to pull Jalter this early on, I have 164 Saint Quartz left to spare at the moment. I'm probably going to hang on to them in preparation for Beach Tamamo and Merlin, though I might give the Cu Chulainn Alter banner a try to see if I'll get Cu Chulainn Alter.
As for my Jalter, she has already reached her 1st Ascension and is currently Level 54. I don't know how quickly I can get her to her 3rd Ascension to unlock all her skills, but I'm currently trying to do my best to have her reach that point as soon as possible (as well as hopefully clear out the Hearts of the Foreign God in the Da Vinci event shop because she and a number of my other servants will need it). Now to think of a team for her...
