First Conquest of Azeroth party

Updated: 2026-10-04. The project owner selected these five classes as the first CoA implementation milestone. Build and refine this party before expanding to other CoA classes. CoA here means Conquest of Azeroth on Vol'Jin; the existing RoM backlog's Chronicles of Arcadia references describe a different game.

Seat	Class	Initial specialization	Responsibility
1	Guardian	Vanguard	Tank
2	Witch Doctor	Brewing	Healer
3	Barbarian	Brutality	Melee damage
4	Ranger	Archery	Ranged damage
5	Pyromancer	Incineration	Caster damage

Begin with each class's core kit and the selected specialization so the full party can enter targeted playtests early. Finish the remaining trees within these five classes before expanding to the other classes. This selects work; it does not certify the current implementations.

Implementation order and acceptance

Freeze the five class/spec identities and reproducible diagnostic inputs. Inventory every node, rank, source spell, and current runtime mapping. Author reviewed talent allocations instead of treating generated role-weighted allocations as an intended CoA build.
Establish the tank and healer loops together, including their resource and persistent state. Check damage, mitigation, threat, healing recipients, periodic effects, and party utility against the captured evidence.
Implement the three distinct damage loops and their talent interactions. Share combat primitives where their semantics match, while keeping class state and learned-rank ownership on the correct actor.
Test the same party against explicitly selected encounters. Repeat with each class as the active player and the other four as companions. Include single-target and multiple-target pulls, incoming party damage, interrupts, dispels, cooldown use, resource exhaustion, death, and resurrection where the selected kits provide them.
Fix observed mechanic and AI defects, then inspect live dungeon play and record evidence in PLAYTEST_NOTES.md. Compare balance only after mechanic correctness. Expand the selected classes' other trees before other classes.

The completion gate is verified behavior for the reviewed core/initial-tree builds on players and companions, a coherent 1-tank/1-healer/3-damage party in live playtests, and an explicit record of any unresolved source limitations. Catalog counts, a boss kill, or passing preparation tests are insufficient.

Source-backed priorities

The following anchors are from the August Vol'Jin capture in src/game/coaLiveData.generated.json. They identify work to verify; they are not claims that these mechanics are implemented.

Guardian: Footman's Calling (node 4019, spell 92105) establishes formation behavior; Vanguard's Shield (34417, 804383) builds stacks through blocks and auto attacks; Paragon (29969, 706514) transforms Heavy Blow at 10 stacks and interacts with Brace. Audit formation gates, actor-owned stacks, block events, threat, and defensive sequencing together.
Witch Doctor: Cauldron Brewer (4005, 92085), Ingredient: Jungle Shrooms (12645, 801660), Potion Toss (12646, 801661), and Mixologist (6645, 561069) establish cauldron/ingredient state, nearby ally effects, and ingredient-based changes to a targeted heal. Verify recipient, radius, periodic cadence, ingredient exclusivity/capacity, and healing formulas before adding interactions.
Barbarian: Decapitate (5744, 804414) requires a target below 35% health and converts additional Energy into damage; Beheader (6744, 705222) refunds Energy after an eligible kill; Battle Rhythm (14303, 800193) generates Energy on ability critical hits. Verify event origin and payment/refund ordering.
Ranger: Precision Shot (31178, 500075), Hunting Shot (29660, 801191), and Masterful Archery (7794, 680469) depend on Advantage, Elude, ricochet hits, and stacking effects. Audit the state and target selection before AI priorities.
Pyromancer: Ignite (6985, 800791), Combustion (29854, 520884), and Pyroclasm (7174, 520019) depend on Heat, Embers, and the caster's burning effects on a specific target. Verify periodic generation, spending, effect counting, and effect consumption. The August Agonizing Burns/Timed Attacks payload exchange also requires explicit saved-build review.

Current generated resource profiles and generic effects do not prove these stateful loops are supported. Unspecified proc timing, missing coefficients, and unknown server rules remain evidence gaps; never invent their values. Use the cached Vol'Jin capture and global Spell data described in COA_REFERENCE_PIPELINE.md.

Repeatable preparation and targeted diagnostics

src/game/coaFirstPartyRoster.ts owns the exact roster. The benchmark helper at src/game/benchmark/coaFirstParty.ts owns build selection, companion construction, and explicitly scoped Balance Lab configurations. scripts/coa-first-party/prepare.ts produces the review inventory and five active-player configurations, retaining the same party build IDs in each.

npm run coa:party:prepare -- --list-bosses ragefire-chasm
npm run coa:party:prepare -- --level 60 --boss <exact-key-from-list>
npm run coa:party:test

Preparation writes ignored local artifacts to artifacts/coa-first-party/level-60/: audit.json, audit.md, config.json, and seat-1.json through seat-5.json. It records the source capture/hash, legal generated talent allocations, source gaps, and runtime representations. Every mechanic begins as needs-review; mapping is not verification. It downloads nothing and runs no encounter simulations.

Once an explicit diagnostic is appropriate, the existing runtime consumes a prepared configuration without changing the ordinary companion pool:

npx vite-node --mode balance-lab scripts/balance-lab/runtime.ts simulate --config artifacts/coa-first-party/level-60/seat-2.json --output artifacts/coa-first-party/level-60/seat-2-runs.json

Only the selected five and explicitly named bosses belong to this milestone's diagnostics. All five remain Needs Testing. Do not change Ready policy, random/eligible pools, default regression scope, or all-class sweep coverage. Ordinary live party generation currently uses the Ready WoW pool, including for a CoA player; a complete CoA party must be configured explicitly.

For implementation changes, run the smallest affected tests plus the existing Ready-five checks, build, and npm run release:check. Record each mechanic's source, player/companion checks, and live evidence as it is completed.

Initial implementation and evidence limits

The first catalog fix exposes sourced active Talent entries for these five classes. Talent Essence purchase type no longer prevents an active spell from becoming a usable action. The action retains its talent-node/rank gate. DBC passive flags and rank metadata keep passive Talent nodes on the existing modifier path; missing DBC rows cannot create a new action. The other 16 classes retain their previous action catalogs.

This fixes action availability, not the complete effect of each spell. Initial Potion Toss checks cover its base targeted heal and mana payment for a player and companion; ingredient riders and its full authored scaling remain work. Decapitate's target-health gate is a separate first mechanic; additional Energy conversion and the Beheader refund remain pending.

Ranger's primary resource is now Focus, matching its spell costs. Player and companion checks cover spending, the displayed/authoritative pool, and recovery. The existing authored 100-point pool and 10-per-second recovery are retained; this correction does not establish source-verified regeneration or implement Advantage/Elude.

Brewing has specific evidence limits beyond the node-rank source inventory: Mojo Beam's capture describes eight seconds while the selected DBC says four; Spirit Link Idol's tooltip says fourteen seconds while its DBC says 8.5. The current promoted catalog omits the Loa's Blessing empowerment payloads 802207/802208/802215/802216 and Spirit in a Bottle's referenced 504606/707172 payloads. Resolve those exact references against the local/raw cache before implementing their full behavior. Zero missing node-rank DBC rows does not establish that every mentioned payload or server rule is known.

Kickoff validation and diagnostic baseline

On 2026-10-04, 87 focused tests across 15 files pass, including the exact roster, learned Talent actions, Potion Toss delivery, Decapitate's health restriction, Ranger Focus, source scope, and classic catalog preservation. Ready-five checks pass seven game tests and twenty Python tests. The production build passes TypeScript, asset audits, bundling, compression, and bundle verification. npm run release:check passes, including untracked files. A before/after digest also confirms the other 16 CoA action catalogs are unchanged.

The targeted automated baseline uses the same five generated level-60 builds, seed 1, and Taragaman the Hungerer (ragefire-chasm/entry-11520). Each run has a 30-second limit and moves only the active player seat. Results after the Focus correction are:

Active player	Outcome	Elapsed seconds	Boss health remaining
Guardian	Time limit	30.0	80,065
Witch Doctor	Time limit	30.0	79,292
Barbarian	Defeated	12.6	0
Ranger	Time limit	30.0	12,782
Pyromancer	Time limit	30.0	14,724

Raw runs are local ignored artifacts at artifacts/coa-first-party/level-60/seat-1-runs.json through seat-5-runs.json. Companion action counts are substantially lower than player counts; Ranger and Pyromancer companions each cast only three times in the healer-seat run. That run's Ranger still records 32.3% Focus starvation. The profile correction alone does not resolve their rotations, stateful costs, or generic effect semantics. The large player-seat differences require mechanic and AI investigation before balance changes. This low-pressure encounter also provides limited evidence for tank/healer interactions.

These are explicitly scoped automated diagnostics, with no live browser playtest or balance certification in this kickoff. All five remain Needs Testing. The next implementation pass is Guardian's Vanguard state together with Witch Doctor's cauldron/ingredient loop and reviewed talent allocations, followed by the three damage loops and companion rotation parity.
