Oh, I see what you did there, huh. At first I was confused if pickaxes and axes are forbidden the entire playthrough, but looks like you just meant, you don't start with them. Which means that bombs are pretty crucial at first, but then you can make these tools from the ores/bars you gather?
Is this master mode by the way?
I did a "
start in hardmode challange" too, several months ago, but that was normal mode, after I got upset with it takes ~200 swings with wooden sword, to kill a blue slime. But on normal mode, it was a pretty fun challange.
I did used normal tools though, and didn't start with anything special, just the usual copper tools.
Look through that thread if you want.
Either way, I think challanges like this are fun, yeah.
You could just bought an anvill from the merchant though XD And you could, alternatively use metal bars you find in chests, to make your missing tools there, if you find any already made metal bars. If you found bombs though, yeah, it's easy to gather stone for furnace, and metals too. (or build a house for him in the jungle where he sells the furnace)
You won't wanna rely too much on those pre-hardmode metals though probably.
You would have trouble smashing altars, but you can fish for crates with hardmode ores! You could get some pretty nice stuff. Weapons, tools, armor, and even some other gadgets too.
Ah, and, another thing to keep in mind (if you plan to spend longer in that world), is, that whatever evil biomes you have there will spread like wildfire now! Quaranteening them might be high priority.
Also, you won't have hallow generate (if you made the world hardmode via T-edit, and not via killing WoF), but you can make artifical hallow with hallowed seeds and also with other stuff.
Anyway, nice video! And keep up the good work!
