I spent every fate weave ticket and almost every magia stone I had (306 rolls total) in the name of my goddess Ultimate Madoka... and I managed to 3-slot her! My original goal was to at least 2-slot her, which I managed to do after 164 rolls without being spooked by a different 4-star magical girl. I kept going, reached pity the third time around, avoided being spooked, and then I emptied the remainder of my stash and got nothing. After I complete my daily missions and grind the materials to awaken her, I'll have enough stones for one last 10-roll to see if I can pull a miracle and 4-slot her.
