Log Rx Guide

Complete reference for Dr. R.O.T and Dr. R.L.D

Demo Mode

Want to see what Log Rx can do? Demo mode lets you explore both tools without logging in. Both Dr. R.O.T and Dr. R.L.D demos are available from the home page - no setup required.

Demo mode uses a pre-loaded sample report so you can immediately see the analysis tools in action. The search bar is locked in demo mode. To unlock full features and analyze your own reports, sign in with Discord and input your free WCL key.

API Key Setup

Log Rx uses the Warcraft Logs v2 API to pull report data. To analyze reports, you'll need to add your own WCL API credentials in Settings. A free WCL account includes API access.

1. Go to the WarcraftLogs API dashboard

2. Click + Create Client

3. Enter any name (e.g. "Log Rx") and https://log-rx.app/ as the redirect URL

4. Do not check the "Public Client" box

5. Click Create, then copy the Client ID and Client Secret from the green banner. The secret is only shown once.

Your credentials are encrypted before being stored and are never shared. Once a report has been analyzed, it's cached and free for subsequent views.

Quick Start

Log Rx has two tools. Dr. R.O.T analyzes individual player rotations. Dr. R.L.D audits the entire raid for a raid leader.

Dr. R.O.T

Rotation Optimization Tool

Paste a WCL report link

Go to Warcraft Logs, find a raid report, and paste the URL into the search bar on the Rotation page. Recently analyzed reports appear in the search dropdown for quick access.

Select a boss encounter

Choose which boss fight to analyze from the dropdown. Only boss encounters (not trash) are shown.

Pick a player

Click on a player tile from the raid roster. Each tile shows class, spec, and their overall raid parse average. Parse averages reflect the most frequent role for players who fill multiple roles (e.g., a feral druid who tanks and DPS).

Review the analysis

The timeline shows your player's rotation side-by-side with the top 10 ranked players. Scroll down for the full performance breakdown.

Dr. R.L.D

Raid Lead Dashboard

Paste a WCL report link

Go to the Raid Lead page and paste a Warcraft Logs report URL into the search bar. Recently analyzed reports appear in the search dropdown for quick access.

Run analysis

Click "Analyze Raid" to start the full audit. All boss fights are analyzed automatically.

Check raid debuffs

Review raid-wide debuff uptimes, sapper usage count, and overall raid health at a glance.

Review the scorecard

Every player is scored and graded. Players with gear issues glow yellow on the left side of their panel. Players with required elements issues glow red on the right side of their panel. Click any player to expand their player card with a summarized breakdown.

Dr. R.O.T: Rotation Timeline

The timeline is the core of Dr. R.O.T. It shows every cast your selected player made during the fight, aligned against the top ranked players for that spec.

Spell Icons

Each cast is shown as the spell's WoW icon. Hover to see the spell name, timestamp, and whether it is a cooldown ability (Gold Glow).

Bloodlust/Heroism Windows

Blue highlighted regions show when Bloodlust or Heroism was active. Check if your cooldowns aligned with these windows for maximum output.

Zoom and Pan

Scroll to zoom in on specific time ranges. Click and drag to pan the timeline.

Region/Faction Filters

Filter the ranked players by region (US, EU, KR, TW) or faction (Alliance, Horde) to compare against players in your bracket.

Parse Colors

WCL parse colors represent your performance percentile on an encounter:

Gold: 100 parse

Pink: 99 parse

Orange: 95-98 parse

Purple: 75-94 parse

Blue: 50-74 parse

Green: 25-49 parse

Gray: Below 25 parse

Dr. R.O.T: Performance Summary

Below the timeline, the summary panel breaks down your performance into scored categories:

RPS Breakdown A 4-column breakdown showing your parse, activity %, mechanic fails, and death count with parse-colored values, bar graphs, and weighted RPS scores side by side.

Activity and Uptime How much time you spent dealing damage or healing. Compares your active time and casts-per-minute against top players.

Bloodlust or Heroism Alignment Did you use your major cooldowns during Bloodlust or Heroism? More CDs during these windows means more output. Shows which CDs you missed.

Cooldown Efficiency How many times you could have used each CD vs. how many times you did. Missed uses are highlighted. Engineering consumables like Sapper Charges are tracked separately in the consumables section.

Cast Distribution Spell priority comparison. Shows the biggest differences between your cast mix and the top players.

Opening Sequence Side-by-side comparison of your first 20 casts vs. the top players' openers.

Potion and Sapper Usage Pre-pot detection, combat pot timing, overall potion efficiency, and engineering sapper charge tracking. DPS potions are shown in gold to distinguish them from missing consumables (shown in red).

Buff and Debuff Uptimes How long key buffs and debuffs were active for the selected player. Higher is better. Red indicates below target or missing.

Mechanic Execution Scores how well you avoided boss mechanics using our per-boss mechanic definitions. Each mechanic uses threshold-based detection (hit count, damage taken, death cause, or debuff duration) and is classified by severity. Use "Configure Mechanics" to opt out specific mechanics from scoring.

Death Recap A simple death analysis showing what killed the selected player and the preceding damage events.

Statistical Insights Statistical patterns compared to the top 10 players, grouped by priority: Notable (large deviations), Pattern (moderate differences), and Observation (minor trends). Review and decide what applies to your strategy.

RPS Scoring

The Raider Performance Score (RPS) combines a Performance Grade (90%) and a Required Elements Grade (10%) into a single 0-100 score for each encounter.

Performance Grade (90%)

Four categories are each graded 1-5 then weighted. The default weights shown below are for DPS. Tanks and healers use role-aware weights that emphasize mechanics and deaths over parse:

Parse 35%

50 deaths

23 deaths

14+ deaths

*A wipe event is triggered after the main tank dies and the raid fails the encounter.

Required Elements (10%)

Pass/fail checks. Your RE score is the fraction passed. Weapon buff only applies to classes that use oils, stones, or poisons - classes without an applicable weapon buff show x/5 instead of x/6.

Sapper used No gear issues Weapon buff* Pots used Flask or elixir Food buff

* Oil (casters), sharpening/weight stone (warriors), poison (rogues). Not applicable to all classes.

Final Score

The overall RPS is calculated as:

RPS = (Performance weighted avg / 5) x 90 + (RE passed / total) x 10

Letter grades: S 95+, A 85-94, B 70-84, C 55-69, D 40-54, F <40

Role-Aware Weights

Performance weights shift by role so that tanks and healers are not penalized for lower parses:
