Reaction Setup

Markets & Pricing

Reaction mode is the default for every alchemy-capable material. In Step 3 · Pre-React you compare the standard vs alchemy build cost side by side for each material in your plan and choose which to use (per reaction, or per stage) before shopping.

Market Skills & Standings

Base broker fee 3.0% · base sales tax 4.5%. Set standings to 10 in Imperium markets.

How it works

  1. Set up your slots, skills, build system and pricing here.
  2. Pick Reactions: enter instances of each complex reaction to run.
  3. Pre-React: compare standard vs alchemy per material and choose.
  4. Shopping: buy everything on the aggregated list.
  5. React: run the build-up phase, then the full chain for ISK.

Intermediates auto-pick the cheaper of build-vs-buy, and market fees are charged once (on sale) — so Step 2 and Step 4 agree.
