About This Tool

The tool enables disciplined item planning for MOBA players by capturing champion context, patch version, and budget constraints. It computes builds that maximize stat efficiency while respecting item slots and recipe dependencies. Users can compare multiple build paths in a structured way, including alternative items for contingency and meta shifts. Conceptually, the system aggregates per-item stats, applies synergy and role baselines, and performs a constrained search to produce a ranked set of candidate builds. The core value lies in reproducible, patch-aware guidance that reduces guesswork and accelerates coaching prep. Typical use cases include pre-match prep, patch analysis, and content creation where repeatable build pipelines matter. Core features include a catalog of items with costs and slot requirements, slot-constrained optimization, and exportable results for sharing with teammates. The tool emphasizes data fidelity (accurate costs, correct slot rules, patch alignment) and supports advanced users with bulk comparisons and presets. By design, it decouples UI from logic, focusing on the domain reasoning and reproducible outputs that analysts rely on for strategy discussions and training drills.

How to Use

  1. Provide inputs: select champion, role, patch_version, budget_gold, and slot count.
  2. Load catalog and constraints: ensure item catalog reflects the patch and role.
  3. Run calculation: generate ranked build options within budget and slots.
  4. Review outputs: inspect total_cost, stat_totals, and synergy scores.
  5. Export: save the selected build to JSON or share with teammates.

Frequently Asked Questions

Find Quick Answers

How is the build score calculated?
The build score combines stat efficiency, slot fit, and synergy with the chosen role. Each item contributes base stats, then pairwise synergy terms adjust the total. The score is used to rank builds within budget and slot constraints.
What if patch_version is not found?
The tool will fall back to the nearest available patch catalog and flag a warning. Builds are still produced, but stats reflect the closest patch data to avoid gaps.
Does it account for item costs and budget exactly?
Yes. Each candidate build totals item costs and verifies against the specified budget. If the total exceeds budget, the build is excluded or adjusted to stay within limits.
Can I compare multiple builds side by side?
Yes. The tool supports multi-build comparisons, showing per-build stats, costs, and synergy scores to facilitate quick decision-making.
