Collection I've been trying to collect everything and am still quite far from the goal In short summary here is my progress and I started back in 1.1.(though very nearly done with
weapons - Need Obsidian sword fish and 2 bananarangs that's it... so close to success...
tools-missing saw tooth Shark rock fish and hotline fishing rod
armor-nearly done only lacking fishing armor 2 pieces eskimo armor(counting both sets as pieces) and one piece mining armor
pets-need zephyr fish
accessories-need some angler based ones
mounts -need scaly truffle
grappling hooks-missing the hook form the angler
paintings- missing rares from dungeon as well as some cabin ones
banners-missing rares
boss masks and Trophies -done for now
vanity -mostly done
If you notice I'm mainly missing fishing related items
(I
hate fishing in Terraria)
But in short I have been carried through Terraia by my goal of collection you can't get bored if you haven't met your goal
