Welcome to the ranks of Summoner! I started playing it around a couple months ago and I'm really enjoying it. Looks like the others have already given you plenty of material to get started, so I'll just say that while it may seem like a lot to take in at first, with a bit of practice you'll start getting things down to muscle memory. It's just a matter of getting timings down and progressing through various burst phases with a couple brief downtime spots to prep for the next burst. Good luck, and have fun!
