BG3 Builder

Purpose & User Intent: The BG3 Builder is a domain-focused planning tool for Baldur's Gate 3 players who design and optimize character builds, including class paths, race, abilities, feats, and equipment, to meet campaign goals. Target users are players, dungeon masters, and group leaders seeking repeatable, comparable build options and data-driven trade-offs. Assumption: BG3 Builder refers to a Baldur's Gate 3 character-build planner.
Core Logic & Features: The tool encodes game rules for ability score economics, class progression, proficiency bonuses, spell slots, and feat prerequisites. Required features include a parameterized character model (race, class path(s), level, background), a stat distribution engine (point buy/standard array), a feat/equipment impact calculator, and a build ranking module by metrics such as DPR, survivability, and utility. Optional/Advanced features include multiclass optimization, item synergy scoring, and scenario analysis for party roles.
Inputs & Outputs: Inputs cover identity (name), race, one or more classes, level, ability scores, feat choices, equipment budget, and campaign constraints. Outputs include recommended stat priorities, feat selections, skill proficiencies, expected attack bonuses, damage per round estimates, spell slot progression, and resource usage forecasts. Formatting rules express numbers with standard game units (HP, proficiency bonus, armor class, spell slots) and provide compact build summaries for quick comparison.
Algorithms & Calculations: The tool uses point-buy math for ability scores, scales class features with level, validates prerequisites, and renders optimized options according to chosen goals (max damage, durability, or utility). It returns ranked builds with trade-off notes and clear rationale.
Error & Edge Cases: Handles missing required inputs by flagging fields, validates level bounds and stat caps, detects conflicting multiclass paths, and warns when data is outdated or inconsistent with current BG3 patch rules. Industry/Region & Localization: Aligns with common BG3 mechanics and patch cadence, using standard fantasy-relevant units; localization is limited to language-specific wording in the UI layer, not core calculations. Assumptions & Exclusions: Assumes a single campaign setting with standard BG3 rules; excludes homebrew content, third-party patches, and non-player-character automation unless explicitly enabled.
