This is actually worse than lava. You monster.
Blazing Pyrotheum is a fluid that is produced when Pyrotheum Dust is molten down. It is the fire elemental fluid. The fluid is very, very hot, and is said to be worse than Lava.
The following table lists some details of Blazing Pyrotheum. The same details for Water and Lava are included for comparison.
When Blazing Pyrotheum is placed down, the way it flows is very similar to the way Lava flows. However, it starts fires much more aggressively than Lava does. Source blocks of the fluid also gradually fall downwards if there are no blocks under them.
Blazing Pyrotheum also interacts in specific ways with some entities or blocks that it touches:
Blazing Pyrotheum can be drunk using a Straw. When done so, the player is dealt quite a bit of damage and gets set on fire for 30 seconds.
Why would you drink that?
