More ridiculous luck starting a new playthrough...
This tiny spot of the map explored yielded...
Platinum Pickaxe
Platinum Hammer
Platinum Axe
Silver Leggings
1 Silver Bar short of Silver Chainmail
Armored Cloud-in-a-Bottle (I love getting Warding/Armored Accessories at the beginning of the game lol)
2 Flare Guns
10 Gold (I found two silver coin bags and 1 gold coin bag, spent 5 gold on the Time Hair Dye)
The Stylist NPC who spawned in that small spider cave and luckily only two spiders were there and they only hit her once.
2 Spears (the only reason I was able to kill said spiders)
Aglet
3 Golden Chests (the aforementioned items)
4 Brown Chests (the fourth one just had an umbrella in it)
Topaz Grappling Hook
2 Heart Crystals
All of this in about 45 minutes of gameplay and that tiny, tiny area explored above. The vertical shaft near the NPCs that I dug, I did that after finding all of the above; I started building my house, and already have 5 rooms done, and was building the crafting area when I decided to take a break (I have to go to work soon).
