is it more efficient to farm melons one row or two rows at a time (i dont have macro) (yes using a melon sword)
Since they are not instant break, 1 at a time is faster. You immediately start on the next melon that way. With 2 rows at a time, you break the melon, then start on the one behind it, then switch to the other row, wasting a bit of time with every switch.
1 row. Also get macro and copy an online autominewalk script for an easier time. Either with or without still 1 row tho
