I am certain I had to buy keys for the CB missions, my team was not very good then. And definitely manual past the force dungeons lol, as I was extremely magic heavy with no damage dealers at all. My combined level 20 dungeon times were possibly record setting in the wrong direction. If you want any tips for Spider/FK happy to help, I have used some very unconventional teams... lol.
Thanks, might take you up on that later, though I'll make a new thread for it. I'm still missing one measly rare for the Relickeeper summon, so I'm pretty stuck there for now anyway. By the time I reach the last few missions, hopefully I have some more options for building teams. For example, I pulled Sethallia during the 2x sacred event a few days ago (another magic support...), and her kit (A2 in particlar) looks like it could help me tank spiderlings with the heal + cleanse/block poison combo. The other dungeons is probably mostly a matter of getting some better gear, and hopefully expand my hero pool with some non-magic affinities.
