Demon, level 56, 20 life fruit used, level 5 water shield, 20 points invested in vitality, titanium mage armor, warding obsidian shield, and armored bundled of balloons, and I get 3-shot by Skeletron Prime's melee attacks (vice and saw). I'm not even on Expert Mode. And it's not like it's close to a 4-shot, I'm taking almost 800 damage (I have 1850ish HP), so my campfires don't really help. And even with the boss ichor debuffed, it takes me over 3/4 of the night to beat it with how much I need to focus on dodging, and I just can't dodge that consistently. Do the bosses level with you or are they static level? If they're static I'll try grinding and getting 20 more vitality, but if not, IDK what to do.
Do I keep my T1 class if I get a T2 class? I want to be a Templar and a Mage, but IDK if I can.
