Thorium ore is *everywhere* in the caverns... The thing I will miss is the Life Quartz. Life Quartz still only spawns in very small groupings, and it's quite nearly as common.So, I see Bag of Potential was removed and the only way to get Thorium Ore now is from world generation. Has low generation of the ore been buffed like in the tAPI days to account for this? Got girlfriend into playing Terraria and wanted to show her Thorium, but wanted to start her out in vanilla. We made some progress and didn't feel like starting all over just for the ore. So, if we were to make a new world, would the ore still be low or would we just have to skip it altogether until later on when we have better tools for excavating a new world with the ore?
Also, if you go from vanilla to Thorium, you will be lacking more than just Thorium ore. You would most likely not have the Aquatic Depths biome in the ocean, among other small things here n there. And you kinda would need that if you want Abyssion at all. Good loot there
