Graveyard Keeper 2 Tech Points — How to Get Red, Green and Blue

How do you get tech points in Graveyard Keeper 2?

Four ways. You study items at the Study Table, you gather resources, you finish crafting recipes, and you consume certain items that pay points on use. Every one of those channels feeds the same three pools, and the pools are not interchangeable — a node that wants red will not take your surplus green.

The Study Table is the largest single channel by a wide margin, but it is also the only one that costs a second resource to use. Paying for it means farming Science, which comes from the same writing and alchemy chains that the blue tree unlocks.

Which colour of tech point is the real bottleneck?

Red, and it is not close. The five branches demand 11,157 red, 5,129 green and 4,132 blue in total. Studying every researchable item returns 5,105 red, 6,470 green and 5,385 blue — so research alone covers green and blue with room to spare, while red arrives at just 46% of what the tree costs.

That single ratio should drive your planning. Gathering, crafting and direct-use items are not optional extras for red; they are the majority of your red supply. The full branch-by-branch demand is in the tech tree overview.

How do you get your first blue tech points?

From the Study Table in the church basement, which is the first place blue points appear. Before that table is running you cannot meaningfully enter the blue-heavy branches, and this is why the Writing Basic and Writing Supplies research matters so much early — Writing Supplies is what opens Clean Paper, Ink and Science Kit I.

Once the table exists, blue comes from studying everything you can reach. Recipes give blue as well, but the study channel is where the volume is.

Where does the Science for the Study Table come from?

Three items carry Science, and Clean Paper is the one you can mass-produce. Clean Paper gives 1 Science, Science Kit I gives 30 and Science Kit II gives 60. Since each studied item costs between 1 and 50 Science, the kits are what let you chew through a backlog of unexplored materials in one sitting.

Researching also consumes the item itself, and it costs energy — 6 to 32 per study, dropping to 2 to 14 with the Researcher perk. Plan study sessions before you plan anything else that day, because a full bag of unstudied materials is the cheapest red and blue you will ever buy. The Science economy behind that loop is on Science and blue points.

What are all the tech point sources?

The table below collects all four channels in one place, with the published red, green and blue values for each. Where a dash appears, that source does not pay that colour or no value has been published. Treat the ranges as per-action payouts, not per-hour rates.

All six Techbooks share one Printing Press recipe shape — 1 Blank Softcover Notebook + 1 Ink + 1 Story (silver) for the first tier, 1 Blank Hardcover Notebook + 1 Ink + 1 Story (gold) for Techbook II — and Kraken steak and Fried golden carp both come out of crafts.csv → crafts_in = kitchen_oven, kitchen_oven_t2.

What does gathering pay per action?

Gathering pays in small amounts, repeatedly. Mining stone and ore pays 1 to 3 red per node, chopping a tree pays 0 to 2 red and 1 to 3 green, pulling a stump pays 0 to 1 red and 1 green, and clearing a bush or picking berries pays 1 green. Garden beds return 0 or 2 green.

The two odd entries are graves and beds. Digging graves and burying bodies pays 2 red each, which makes the graveyard itself a red source, and it is the only gathering action that pays a flat red amount rather than a range. Over a long game that adds up more than most players expect.

Which crafted items give the most tech points?

Marble Fence I and II top the list at 15 red per craft, with Master Armor and Master Sword at 12 red behind them. On the green side Chocolate pays 10 green, and on the blue side Marble Cross II and Marble Fence II each pay 15 blue. Those are the highest published single-craft payouts.

The pattern worth noticing is that the best point crafts are also late-game items. You cannot push red with marble before the stonemason and marble quarry lines exist, which is exactly why the mid-game red shortage feels worst right before those chains come online.

Which items give tech points when you use them directly?

Six Techbooks plus five meals, and no others. Each Techbook pays one colour only: Red 25 and II 50, Green 25 and II 50, Blue 25 and II 50. The four dishes pay more: Heavenly salmon, Kraken steak and Fried golden carp each pay 50 of one colour, and all three are oven dishes, so check the crafting stations list.

The meals are not tripled, and this is the number most guides get wrong. Elder’s meal carries three separate entries, one per colour, at 30 each: 30 red, 30 green and 30 blue. Fisherman’s pie is the same shape at 10 each: 10 red, 10 green and 10 blue. The panel prints one figure per colour, and the item pays exactly those figures — there is no multiplier and no hidden third payment. Since every one of these eleven items is also a sellable good, what the fish and Story inputs cost you is on item prices and selling; full per-item research yields are on science research yields.

Do you have to research every item?

Not for the tree to be affordable, but skipping research is the most common long-term mistake. Research supplies 5,105 of the red you need, reveals the alchemy runes on every material you study, and pays blue that no other early channel matches. Selling or discarding materials unstudied trades a one-time payout for permanent scarcity.

There is no research cost to consider twice: each item pays once, and higher-quality versions pay again as separate entries. Cramming materials into the alchemy recipes before studying them is the other half of this problem, because unstudied ingredients cannot be identified at the lab. If you are still early, the beginner first week guide sequences when to research versus when to push tasks, and the energy and insanity guide explains why long study sessions need feeding first.
