What is it that you do just after you start hardmode? I have now played several characters with different ways to at least moon lord and now latest I just started hardmode. Its always at that spot when things grind to a halt. Your gear isnt good enough to fight mechanical bosses...at least it will be difficult.
I can spend large amount of time to get armor and weapons from new ores and that will barely allow me to fight the bosses (at least for my skill level). This is what I have been doing, but this portion feels such a chore.
You cannot even fight most enemies you need to get trough properly.
You dont have hardmode accessories yet and it may take time to get them.
So you just dig... dig... dig and try to find those new ores with help of spelunker pots.
I have been thinking perhaps I should just grind the normal enemies that spawn underground and collect souls of light/night and then use them to craft keys to generate mimics so that can get some rare and actually very useful items. Is this what I should be doing?
So far I have just grinded the basic sets from new ores and used relevant weapon. Then with difficulty I have killed one of the mechanical bosses and then from their drops I can easily kill next ones and get all the things I view being basic hardmode items that makes things flow better.
