Crop Rotation Optimizer

Find optimal atlas passive configurations for Harvest crop rotation

Crop Rotation Atlas Tree

The example trees below use Y-10% B-45% R-25% reductions. Adjust based on the optimizer's recommended values for current prices.

Standard Tree → Use when Sacred Grove spawn is not guaranteed

Guaranteed Grove Tree → Use with Harvest Scarab or guaranteed Grove spawn

Boosting Lifeforce Drops

Pack Size is a direct multiplier for lifeforce. Seeds spawn extra monsters based on pack size - for example, 50% pack size means each seed has a 50% chance to spawn an additional monster.

Map Quantity also affects lifeforce drops at 50% effectiveness. Consider using an Influencing Scarab of Hordes to boost Eldritch Altar spawns, which can roll quantity modifiers to further increase your lifeforce yield.

Memory of Panic

Originator Maps can come with the Petal Skill "Memory of Panic", which can be used on Harvest monsters to make them drop lifeforce a second time.

Important: Memory of Panic must be used on Harvest monsters while they are still alive. It will not work on T4 (Boss) monsters as they are Unique enemies.

Assumptions & Methodology

Data Source

Seed distribution and mechanics are based on ForgottenArbiter's Harvest Mechanics Research.

The default settings err on the side of caution - actual profits should be slightly higher than calculated.

How the Optimizer Works

The optimizer uses dynamic programming to find the best harvest order for any grove state.

At each step, you choose which plot to harvest. Harvesting gives you lifeforce, upgrades seeds of other colors, and may cause the paired plot to wilt. The DP evaluates all possible choices and picks the one with highest expected value.

Mean-field approximation: Instead of simulating random upgrades, we assume all seeds upgrade by their expected amount. For example, if T1→T2 has 25% chance, we treat it as each T1 seed becoming 0.25 of a T2 seed. This gives exact expected values without Monte Carlo noise.

Color weighting: Your atlas reduction settings affect how often each color appears. We enumerate all possible grove color patterns, weight each by its probability, and combine the results.

Mono-color optimization: When the DP reaches a state where all remaining plots are the same color, we short-circuit with an exact calculation. Since harvesting same-color plots doesn't trigger upgrades, we compute: for single plots, E[LF]; for pairs, E[max]×wiltProb + 2×E[LF]×(1-wiltProb). This captures the "pick the better one first" advantage using Monte Carlo-derived E[max(LF₁,LF₂)] at each upgrade level.

Advanced Settings

Upgrade probabilities, drop rates, and lifeforce-per-drop values can all be adjusted via the "Advanced" toggle. The defaults are conservative estimates from community research.

45% Reduction Requirement

At least one color must have 45% reduction to ensure frequent color switches for effective upgrading.
