I'm wondering if it is possible to make a mod where you tap and use Flint&Steel on the ground and it creates stationary lava? It should be nerfed into 4 uses only though, because it would be op with the 50+ uses the original durability has, and it should be stationary lava to represent the "fire" only taking up one block of space. The reason why I am saying it is not making fire is because fire doesnt really harm anyone anymore. This mod involves "blocks" already in the game, so is it possible?
Another idea:
Tap a lapis lazuli on the ground for water!
This idea could be good for an alternative of buckets.
