Forager Guide

My order
i've a construction of 48 lighthouses at the screenshot. There are even extra easy, as you may see at the screenshot of the opposite Forager participant. I take his facts later here.
I counted the lighthouses vertically. each variety represents a column.
five/7/eight/8/three/3/3/eight/3 = 48
opportunity Order
given that lighthouse range is 14 (from the centre block) and size is three*three, evidently sixty four is the absolute maximum quantity of lighthouses you could suit round a three*three island so that the vital block is within variety.
rough calculations gives me that one slime king were given me ~287 billion coins (from promoting all of the 4 coloration gem stones and jelly with grasping potion and merchant shrine buff). which means if you're loopy sufficient to make 64 lighthouses, you could attain a trillion in just 4 slime kings.
In contrast I also did 1 minute of skeletons and that they best got me ~500 million (from ~10mil bones and ~800k splendid skulls), so it really is that.
Messed around with it a bit more. It appears to rely upon the very particular position at the island plenty. i can get anywhere from 36mil to 145mil of each of the gems from every slime king.
