Material Physics
Material Physics reduces construction costs and shipyard timers.
Quick stats
| Effect at level 1 | Bonus |
|---|---|
| Ship and defense resource discount | −20% |
| Building and facility resource discount | −2% |
| Ship and defense build-time reduction | −5% |
Each reduction caps at 99%. At level 5 the tier adds another copy of each initial discount before compounding. Discounted materials round up; construction quotes show applicable modifiers and separate Credit payments. Research is paid with RP.
Cost and access
Available from level 0 without a lab or research prerequisite. Level 1 costs 88 base RP; later levels grow exponentially before any other-domain tier surcharge. The Research screen shows the current quote and saved funding.
Purchase a completed level immediately with RP, or use automatic investment. Metal, crystal and deuterium are not research payments in 3.0. Physical Research Labs increase RP income, not purchase speed.
Each fifth level adds another initial amount before compounding the bonus itself by 1%. See tier progression.
When to invest
Invest before a major fleet, defense or infrastructure build. Compare the next percentage point with its RP cost and your expected construction spending; a discount is useful only when you build.
