I decided to make a infinite source of lava by using dripstone blocks,pointed dripstone and a bucket of lava
when im done making it
i waited for a few minutes to see if the cauldron is being filled up then i notice why it takes so long so i waited for more mins because im thinking that the process can be slow.
and i realized its been 2 minecraft days and the cauldron is still empty so that i came here to report this as a bug
It works, there is only a 5% chance of a lava cauldron filling from drip stone per drip. For you to have a decent return rate, you should set up a 2x2 or 3x3 drip area. Water is a 17% chance to give 1/3 cauldron per drip.
