Hey! Uh, my bad for not updating, so I'll just update days 2,3,4,5,6 here. Day 2: I got way too lucky and got a slime staff. Day 3: Made a hellevator and spent way to long getting obsidian armour just to realize it doesnt have a summoner set bonus in 1.4.0.5. Day 4 and 5: Didnt play. Day 6: Tried to fight myself multiple times, and died a lot.
For Mage I'd absolutely recommend a magical harp or Nightglow from the EoL.
Good luck!
