Relatively new to the game, but I learn quick, and I managed to hit level 50 on adventure mode with a summoner (not a huge feat I know, but it's my first level 50 and I started about a week or two ago). I had fought Atamathon on my invincible archer earlier at sub-level 40 and killed him (remember the part where I was invincible? Yeah that was from a bug, not voluntary, and it's even on exploration mode on that toon), so I decided to try my hand at him on this summoner. I had a ring of the dead, but no lives left. I managed to get him to 75% without taking a scratch--I was stunlocking him with confuse, slow, daze, and pin (grand arrival, wild summon, and detonate were the cause of these). Then he shot me with a rune and I took a ton of cold damage and got frozen. Thinking that would be the main threat, after I contained the immediate situation, I switched my ring of the dead for a ring that would help against cold and freeze (herpderp). I get him down to 25% hp eventually, and then he suddenly uses Giant Leap and one shots me with 1900+ arcane damage and a bit of physical damage (irrelevant, my max hp was 1600+) out of the blue.
Oh well! Guess I'll try a new class--at least I unlocked a !@#%-ton of stuff on that playthrough.
