Plants are all grown in farm plots.
Not correct. Some plants that the world generate throughout the biomes and in the POIs are considered wild plants
So my understanding of Living off the Land is that without it you get 1 crop per plant.
1 point doubles that to two and then a further point gives a 50% chance each harvest to get a 3rd crop.
Which gives 3 at most ?
No.
Wild plants by default give you one crop per plant. Player planted crops give you two crops per plant by default (default = LoTL level 0)
LoTL Level 0 = default crops per harvest
LoTL level 1 = 2x crops per harvest (wild = 2, planted = 4)
LoTL level 2 = 2x crops per harvest, 50% chance for a bonus crop (wild = 2-3 crops, planted = 4-5)
LoTL level 3 = 3x crops per harvest, 50% chance for a bonus crop (wild = 3-4 crops, planted = 6-7)
Ah just been ingame and checked that and did get 4-5 crops per plant again with very few seeds but looks like its just a numbers game rather than a guaranteed like it used to be.....putting that 3rd point in LOTL would really make it work well.
I suspected you didn't get your numbers from the actual game and this proves out my assumption.
The changes mean that you can't create a farm without investing any perks in LoTL which is what the Devs were shooting for with these changes. Prior to A20, there was very little effort required to get a thriving farm. Now if you want to generate a farm to feed you and your party, one member needs to invest into LoTL for it to be viable.
Seeds are 50% drop chance. Sometimes you may harvest 2, sometimes 8 (based on 10 plots); but overtime the numbers should come closer to 50%. You will get a harvest where a lot of your crops will have to be converted to seeds to replant, other times you will barely need to make any seeds.
Don't convert plants into seeds until you are LoTL 1 at least. I typically wait until I got LoTL 2 before I start my farm in SP.
