I am not sure if I would want this implemented into Minecraft. I think it would be best as a mod or in the world generation features. If it was in the world generation features, it would be like this "Hardcore Nether: on/off". Clicking it would change the on/off status as normal. It would be a great mod and would be hugely popular, but would be hugely unpopular not as a mod, for new players or cautious players (like myself) would find the nether unbearable. I would never venture to the nether to do anything. My only other point is that salamanders are amphibians not lizards as you said is the description.
I highly support this amazing thread, though have to admit, the soul glass tools are too OP. It's basically as easy as making tools out of glass, which may break quite easily, but it is almost as powerful as a diamond sword, and, inflicts the victim with slowness. Though, I still support this incredible thread highly.But please ask for fire aspect squid swords too.😏
