@Xkeeper I've not done much with traps and wiring myself, favouring just getting through all the bosses and also trying to collect armour sets for display.
I've recently stopped playing again (saves may have been wiped with the OS reset anyway.) At some point it in playing through it starts irking me how much stuff involve drop chances and/or rare creatures. Building doesn't do much for me in Terraria either.
@BatElite Terraria lets me automate some of the grinding; it's fun making silly traps that let me just put it in park for a while
