About
Luminary is a battle calculator for Eclipse: Second Dawn for the Galaxy.
Battles
Luminary supports a defender and up to six attacking fleets. In a battle with multiple attackers, combat starts at the bottom of the fleet list. The winner continues upward to face the next fleet, carrying any damage from the previous engagement.
Whenever possible, Luminary calculates every dice outcome to produce exact, deterministic odds. Battles that are too complex to solve within the interactive limit automatically fall back to a 5,000-run Monte Carlo simulation. The method used is shown with the results.
Damage Planning
Optimal targeting evaluates legal damage assignments for both sides and chooses the assignments that give each fleet its best chance of winning. Max DPS removal instead prioritizes taking enemy damage output off the board. NPC applies the official NPC targeting priorities to any fleet. Ancient, Guardian, and GCDS fleets always use those NPC rules.
Sharing and Table Play
Every setup is saved in the page URL, so you can copy a link or a chat-ready results summary. Your latest setup and recent battles are also kept in this browser, and the calculator works offline after its first load.
