Placing gravel or sand under your legs while bridging,
Getting exploded by a ghast,
Getting knocked off by a projectile while bridging over a lava lake,
Swimming in lava,
Getting attacked by a magma cube,
Hitting a pigman,
Unloaded lava when you enter the nether,
Getting shot by a skeleton,
Withering away,
Getting burned to death,
The portal spawning on gravel over lava,
Want me to keep going?
