Bismuth Buffs
Phantoms in Bismuth become faster but burn in the sun faster and more lethally.


 * Phantoms in Bismuth Armour gain Speed I
 * Phantoms in Bismuth Armour take 3 hearts of damage per second during the day

Strategies

 * If you have firework rockets, you can fly with them. Although you burn during the day, you have insane mobility at night or in nether, so it is recommended to stay in nether if possible. You can't wear netherite and you don't need torches to branch mine for diamonds comfortably, so you should focus on getting large quantities of those. Bismuth armor gives you speed, allowing for even faster travel and branch mining, so it is advised to get it.
 * Slightly looking down when gliding downwards, then jerking upwards when hitting the ground will give you a burst of speed.
