This initially started as a way to make use of my ship while waiting for ph8, since I didn't want to kill off my Santabrutenclaws fishing for BP (still sad he got replaced with ching when she came out :c ) So the general idea is this: Cross as many squares as possible, in the shortest amount of time, while using up your entire ship's range. Each square you cross has a chance to give you a reward. So by doing as many as possible, you're maximizing the number of rewards you can get. One of these rewards is gems!! There are a couple different paths I've done, depending on where things spawn and if I'm trying to avoid battles (battles take up a lot of range and time, for much less reward, but you may want to clear your initial farming path) My latest path is as follows: Notice it uses all my range and crosses a large number of squares, but only takes 2 hours 3 minutes (with observatory). This is the aim. While a couple things did spawn in my path, because I set sail before they spawned, they did not add to overall range restrictions (unsure if they added time). Notice how many rewards I'm getting from crossing squares. This run I only got 1 gem square, but it had 5 gems in that square. On average, I see 1-3 gem squares; sometimes I get 4, sometimes I get none. The depth of the water effects the number of gems that can be dropped, and I've found the second and third shallowest waters are the most efficient in terms of gems vs time/range to cross. But the shallowest waters take 5 seconds and very little range, so might as well add them in. If you're going to sleep, it may be worth skipping some shallows to cross a more rough sea, however. I would say I average 5-8 gems a trip. The most I've gotten is 15, and there are some times I've gotten 0. But if I'm diligent enough about resending my ship out, I've been able to pull in 50-75 a day in the past. Not a lot, but enough to gem 6-10 extra armies when farming. And to the high rank players that gem resources, this is an easy way to get gems and resources without costing you a single troop, which might be enough to get you an extra couple attacks or a mine or two reset when you're hurting for grog at rank 900. My farming army takes 8 gems with pc3 (10 brutes 25 gunners- 1 brute 4 gunners x 6, 2 brutes 1 gunner, 2 brutes) which means every trip or two I get an entire free army, or an extra 400-600k of both loots every 4 hours. This is an extra 100-150k gold and grog per hour. 30 days of diligent farming would have been enough to completely speed up PH8 when you first start building it. Which is approximately how long I spent farming gems before it was announced. A huge advantage, especially for a non-spender or light spender. The downside is you're sacrificing approx 2k bp per day from farming fishes, so you may want to build up a bit of a reserve even after you've finished your ac7 and mm3s, or hunt fish while you sleep and farm gems while awake. But if you're like me and have a decent pile of BP and EP to spare, and are looking to speed up your wall farming a little bit, I promise these trips add up after doing 5-10 a day for a week. If anyone finds a better path to use all 1600 range in a shorter amount of time, I'd love to see it.
