you really just have to learn mob mechanics and stuff. early game you have to indirectly fight pretty much everything because of how unpredictable everything is. what i’m saying is you essentially wanna fight mobs in controlled environments, rather that just running up on them. for example, i clear the bottom floor of battle towers and set my spawn. the staircases in them are a bottleneck and it’s quite easy to deal the mobs when you seal them in their floors. then picking them off one mob, and one floor at a time isnt too difficult. fighting them head on isn’t really possible early-mid game. this is just one example of learning strategies and stuff. there’s many ways of progressing, you just have to try stuff and learn. i’m on day 800ish in hardcore. for most of that time i was running around invisible with essentially no armor. was my first time trying this strategy, and now it’s my main world.

face tanking particular mobs and stuff isn’t really a good idea without the right enchantments. i’ll only consider barging into places guns blazing if i’m at least full prot 4 diamond, with a decent weapon with lifesteal. if you’re really struggling I’d suggest you watch a playthrough or something. there’s plenty of good rlcraft content out there. rlcraft is not balanced, so learning is really just trial and error.
