Haven’t played Minecraft in 10+ years, never played dungeons 1. Am level 30ish, can someone explain basic gameplay mechanics? Such as:
What does food do?
Is there any reason to hold onto unique items that are under leveled? Like can they be upgraded ? I have merchant and enchanter at level 3.
Seems like a waste to enchant items below max level (100)?
I keep getting wiped by current story bosses, is it just a matter of grinding? Doesn’t seem to be much strategy other then simple synergy builds… but at level 30ish, doesn’t seem worth it?
Open to all thoughts.
