I've been thinking, that since there are 4 proffesion slots why not add some single-level profesions, here's some examples.
Gardener: Has the ability to plant fruits and spore plants, however, these spore plants are unlike most, they do not have spore-spitting capabilities, but are perfectfor guarding an entrance since I propose that they push the person who did not plant them away from them, good for keeping people away from storage spaces in bases. Not only that but they can create fertiliser and plant fruits. The spore plants and fruit plants appear on the map 72 hours after planting to stop farming your ass off. And the fruit plants are ONE use only, once you pick them they're gone for good, however picking them like this does not add to your gathering cooldown.
-Can be trained at a gardener NPC
-Costs 2000 caps
-The gardener NPC sells fertiliser if you're lazy.
-1Charima characters allowed to take the proffesion (called oddjob for a reason)
-Fertiliser: can be crafted from 2xChem Components and 5xBrahmin Shits
-Fertiliser can be used on fruits and spore plant spikes to create Spore plant Sprouts and Fruit Plant Sprouts.
-Fertiliser could use the bag Sprite, as could the sprouts.
-Dropping the Sprout will make it look like a Xander root
-After 72 hours of being on the ground the Plant "Model" Appears
-Spore Plants are non-hostile, they only push people away when the person gets too close.
-They get shot by town guards if they appear in a town.
-Spore plants can be Dug up with a shovel, thus putting 25 Kg of spore plant in your inventory and then be relocated.
-Since Domesticated Spore Plants cannot move or do hostile actions they do not count towards your companion limit.
Brahmin Herdsman
This proffesion is all about keeping brahmin, this being a really simple one.
-Can be learned at any brahmin Dealer
-2000 caps, or 4000 caps
-The cheaper one gives two Brahmin-exclusive companion slots and increases your global follower limit by 10 (these 10 slots are exclusive for brahmin)
-The second one (more expensive one) gives 5 brahmin exclusive slots and gives you 18 global slots for brahmin only, and you get a free brahmin.
-You can upgrade your cheaper one to a more expensive one for 2000 caps, but you do not get that free brahmin if you only upgrade.
Trapper
-You can learn this one at klamath from that guy in Buckners bar you save from the toxic caves in FO2.
-This costs you 400 caps.
-The benefit of it is that instead of getting one gecko skin and brahmin hide from the corpses you get two instead, and the geckos are not hostile to you until you fire off the first shot.
