Starve.io: Full Lava Gear, but I don't use a bag or book!

Three and a half years ago, Yaruo did lava gear without a bag. See the video here:    • Starve.io How to make lava equipment ...  . Now, I do lava gear without a bag, but I take the challenge further: I don't use a book either.

As you can imagine, inventory management is extremely difficult, and I highlight a couple of choke points. Like in Yaruo's video, I do 2 quests to slightly extend my inventory: kill a sand worm, and explore each biome for at least 1 day.

You might think that just the crafting time of a lava sword and helmet requires a book, or else I would starve, but it's just barely possible! In fact, the only item that absolutely needs a book is the Emerald Machine. Even if lava gear took longer to craft, this challenge would still be possible because beds exist.

I used a relatively new tactic to kill the cave dragons. It relies on the fact that dragons fly back to the cave when you move out of aggro range. Normally, the dragon flies at a slight angle, so you cannot predict exactly where it will land. However, if you go beyond the corner of the cave, the dragon flies exactly to the corner. By putting walls at exactly this location, the dragon is trapped when it lands. It is not quite inside the cave, so it cannot destroy the walls. The quest says to kill the dragon inside the cave, but I actually just need to kill it in winter.

For the lava dragon, I cannot use the same tactic, because I cannot place walls at any of the corners, so I must use an "old style" trap. As usual, I deal most of the damage on the island, then finish it off inside the lava biome. For the second lava dragon, the quest is already done, so I can just kill in on the island. The lava dragon has exactly 3 times as much health as a wood wall, so it's best to use a weapon that deals exactly 3 times as much damage to mobs as buildings, such as a diamond sword.
