k4yfour | alternate slabs - double building blocks (for pillaring or jojoe's perch strats) @k4yfour | Uploaded 4 years ago | Updated 2 hours ago
will see most use while doing jojoe's end pillar strat (link: youtube.com/watch?v=anNaUq2LHyw) as one of the problems found in the strat is that players don't often have an excess of building blocks and have to rely on other methods

can also see use where water buckets aren't practicable or available

common sense once you've seen it
