Today while I was mining diamonds in a cavern I found lava and unfortunately I fell into the lava pool and started to burn. I also died by the lava and dropped and lost MANY items including my enchanted diamond sword, enchanted bow (also the highest enchantable bow), my armor, about 32 diamonds and many iron. The thing that should NOT occur occured. Here is a video when I being killed by the lava:
What should I do to avoid being killed by lava again? The death think I was very hard to avoid.
