Regent Forge & Star Power Estimator
REGENT FORGE ESTIMATOR
Regal Strike
Forge Level 0 and Star Power 0. Balanced attack estimate for comparing early and mid-forge breakpoints.
This tool is a quick scenario estimator for comparing forge paths, not a frame-perfect combat simulator.
How to use this calculator
The Regent operates on a dual-scaling system: Forge (immediate power investments) vs Star Power (delayed exponential scaling). This tool helps you compare the two paths:
- Current Resources: Enter your current gold/star power available for investment this turn. This represents the opportunity cost of choosing one path over the other.
- Forge Investment: Input how much you'd spend on immediate forge upgrades (weapons, armor, or direct damage). This provides now value but delays star power accumulation.
- Star Power Investment: Input how much you'd allocate toward star power scaling. This delays immediate power but increases future payoff exponentially.
- Turn Timeline: Set how many turns ahead you want to project. Short fights (3-5 turns) favor forge, while long fights (8+ turns) often reward star power investment.
- Compare Outputs: The tool shows cumulative damage/power for each path. The crossover point tells you when star power overtakes forge — use this to decide based on expected fight length.
Understanding Regent's dual economy
The Regent is unique among STS2 characters because every purchase decision is a timing bet:
- Forge Path: Invest in immediate combat effectiveness. You get power this turn but delay long-term scaling. Ideal for short fights, elite rushes, or when enemy damage spikes soon.
- Star Power Path: Invest in delayed exponential scaling. You're weaker this turn but disproportionately stronger in 5+ turns. Ideal for boss fights, long combats, or when you have other survival tools.
Key Insight: The Crossover Turn
The calculator identifies the crossover turn — the point when star power's delayed scaling finally overtakes forge's immediate power. If you expect the fight to last longer than the crossover, star power wins. If the fight ends before the crossover, forge was correct. This single number clarifies most Regent investment decisions.
When to use this tool
Regent math gets complex quickly. Use this estimator in these scenarios:
- Pre-shop decisions: Before spending gold, compare "spend 50 gold on forge now" vs "spend 50 gold on star power." The calculator shows which pays off given your expected fight length.
- Elite vs boss strategy: Elite fights are short (favor forge), boss fights are long (favor star power). Run both scenarios to see how different investments play out over different timelines.
- Relic evaluation: Some relics modify forge efficiency, others boost star power growth. Quantify which relic better fits your current deck's expected fight duration.
- Turn-by-turn planning: When deciding "forge now or star power now," use the crossover turn to time your strategy pivot. Many Regent runs succeed by switching from forge to star power at the exact right moment.
Common mistakes to avoid
Mistake 1: Ignoring fight duration
Why it's wrong: Forge dominates short fights, star power dominates long fights. Planning without considering "how many turns until this enemy dies" leads to suboptimal paths.
Correct approach: Before every investment decision, estimate fight duration based on enemy HP, your current damage output, and expected defense. Use the calculator with that turn count in mind.
Mistake 2: All-or-nothing thinking
Why it's wrong: Optimal Regent play isn't "100% forge" OR "100% star power" — it's usually a mix. Pure forge leaves you weak in boss phases; pure star power gets you killed in elite rushes.
Correct approach: Use the calculator to find hybrid strategies. For example, "70% forge early game, switch to 60% star power by Act 2." The tool lets you model mixed allocation scenarios.
Mistake 3: Forging when starving star power
Why it's wrong: In long boss fights, insufficient star power investment leaves you with a linear damage curve while enemy HP scales exponentially. You hit a wall in phase 2 or 3 where forge damage simply isn't enough.
Correct approach: In boss fights, ensure at least 30-40% of your resources flow to star power, even if it feels weak early. The calculator shows when this delayed investment pays off (usually turn 6-8).
Quick investment benchmarks
| Fight Type | Expected Turns | Optimal Allocation | When to Pivot |
|---|---|---|---|
| Standard enemy | 3-5 turns | 80%+ Forge | N/A (fight too short for star power) |
| Elite fight | 5-7 turns | 70% Forge / 30% Star Power | Turn 4 if elite not dead |
| Boss Phase 1 | 8-10 turns | 50% Forge / 50% Star Power | Turn 5-6 toward star power |
| Boss Phase 2+ | 10-15 turns | 30% Forge / 70% Star Power | Turn 3 toward star power |
Rule of thumb: If you expect the fight to last 6+ turns, star power deserves at least 40% of your resources. Shorter than 5 turns? Go nearly all forge.
Advanced strategy tips
Once you understand the basic forge vs star power tradeoff, explore these advanced concepts:
- Deck composition impacts timing: Decks with card draw effects can accelerate star power payoff by reaching key cards faster. If your deck draws 2+ extra cards per turn, you can afford earlier star power investment.
- Relic synergies: Some relics provide free forge charges every turn, effectively increasing your forge efficiency. Factor these into calculations — you might need less gold investment in forge than the calculator suggests.
- Enemy scaling patterns: Some enemies deal escalating damage (favoring star power's faster kills), others have predictable high-damage phases (favoring forge's immediate defensive value). Adjust your allocation based on enemy patterns.
