Log Rx Guide
Complete reference for Dr. R.O.T, Dr. R.L.D, Dr. R.A.T, and Dr. H.R.T
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
Dr. R.O.T analyzes individual player rotations. Dr. R.L.D audits the entire raid for a raid leader. Dr. R.A.T builds and shares raid assignments, and Dr. H.R.T trends your team's performance across lockouts. Quick starts for Dr. R.A.T and Dr. H.R.T have their own sections below.
Dr. R.O.T
Rotation Optimization Tool
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.
Choose which boss fight to analyze from the dropdown. Only boss encounters (not trash) are shown.
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).
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
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. Click + Add log to combine up to 3 reports into one view. No key? Drop, paste, or upload a local WoWCombatLog .txt instead (beta).
Click Analyze to start the full audit. Each boss loads its own analysis and is cached after the first run, so re-opens are instant. The Raid Summary, Raid Breakdown, and Raid Audit panels fill in as the fights finish.
Review raid-wide debuff uptimes, sapper usage count, and overall raid health at a glance.
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:
Dr. R.O.T: Performance Summary
Below the timeline, the summary panel breaks down your performance into scored categories:
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%
WCL parse percentile
Activity 10%
WCL active time %
Mechanics 30%
# of failed mechanic checks (threshold-based)
Deaths 25%
Deaths per encounter (pre-wipe*)
*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/4 instead of x/5.
* Oil (casters), sharpening/weight stone (warriors), poison (rogues). Not applicable to all classes.
Final Score
The overall RPS is calculated as:
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:
Dr. R.L.D: Features
Raid Scorecard
All players are grouped by class with their grade, DPS, and score visible at a glance. Players with issues are highlighted with a yellow and/or red glow so problems are immediately visible.
Player Cards
Click any player to expand a detailed breakdown: per-fight scores, consumable compliance (Flask, Food, Weapon Oil/Stone/Poison, Pots, Sapper), gear issues, deaths, and mechanics.
Sapper Tracking
Detects Goblin Sapper Charge and Super Sapper Charge. Usage appears as a green/red pill per player and a summary bar in Boss Debuff Uptimes lists who missed and who complied.
Raid Debuff Uptimes
Tracked under the Raid Audit panel's Spell Uptime tab: per-boss uptime for Sunder Armor, Faerie Fire, Curse of the Elements, Blood Frenzy, Judgement of the Crusader, and more. Shows who is responsible and highlights low uptime. When a boss spends part of the fight untargetable (submerges, air phases), uptime is measured against the time the boss was attackable and gets a gold "adjusted" chip; hover it for the wall-clock number.
Multi-Log Analysis
Combine up to 3 reports into one view with the + Add log button, so a split-night raid reads as a single audit. Every panel merges the logs; sharing stays single-report.
Combat Log Upload (Beta)
Drop, paste, or use the Upload .txt button to analyze a local WoWCombatLog .txt with no Warcraft Logs key. The file parses in your browser and never leaves your machine. WCL-only stats (world percentiles, RPS grades, gear) show n/a in beta.
Consumable Compliance
Checks flask, food buff, battle/guardian elixirs, weapon buffs, pre-pot, and combat pot usage per fight for every player in the raid.
Drums Effectiveness
Tracks drum casts, buff application success rate, average players hit per cast, and greater vs. regular drum usage per player per fight.
Gear Issues
Detects missing enchants on major slots and empty gem sockets.
Resistance Checks
Auto-detects encounters requiring specific resistances and audits each player against the threshold. Covers Hydross, Leo, Mother Shahraz, Illidan, and more.
Dr. R.L.D: Raid Breakdown
A WCL-style direct extraction at the top of the Raid Lead page, so you do not have to tab back to Warcraft Logs. Pick a scope and read the whole raid at a glance. The panel is collapsible.
Damage, Healing, Damage Taken
Damage Done By Source, Healing Done By Source, and Damage Taken By Player, with class-colored bars scaled to the top performer, per-second values, and full scrollable lists.
Scope Toggle
Switch between Everything, Trash, or Encounters (Kills, Wipes, or Both). Every scope is pre-fetched, so toggling is an instant filter rather than a new load.
Grouped Deaths
Deaths are ranked by player (most first). Expand a player to see each death with its fight-relative time, a Boss or Trash tag, and the killing blow.
Click to Recap
Click any death to open the full death log in a modal: the same damage-and-heals timeline leading up to the killing blow that the per-boss cards and the RPS tab use.
Dr. R.L.D: Raid Audit
A tabbed panel that audits the whole raid across six tabs: Spell Uptime, Spell Use, Consumes, Engi, Mana, and RPS. Pick a tab, then a spell or item and (optionally) a single player; every tab breaks the result out per boss plus a Trash row. Each boss row shows a Kill or Wipe tag with the fight duration, and a "Top users" strip lets you click a name to filter to that player.
Dr. R.A.T: Quick Start
Dr. R.A.T replaces your raid assignment spreadsheet. Build a loadout once, then reuse it every week: players get a glanceable raid-ready view, and raid leads get a WeakAura export.
Click New loadout on the Assignments page and build your roster, or import an existing loadout from JSON.
Build per-encounter blocks for tanks, heals, curse rotations, interrupts, and more, with players pulled straight from your roster.
Encounter maps support per-encounter phases, so positions can change as the fight does: step through phases on the map and neighboring phases show as a faint onion-skin. Decorate the map with icons, arrows, and captions to make movement obvious.
Players open a glanceable raid-ready view filtered to their own assignments. Raid leads can export a WeakAura so every assignment shows up in game.
Dr. H.R.T: Historical Raid Trends
Dr. H.R.T trends your guild's raid teams across lockouts. Every report tagged in Dr. R.L.D becomes a data point: raid, boss, player, and audit metrics, charted week over week. The workflow is a loop:
Run a normal Raid Lead analysis of your raid night's report. That is the only data collection step; nothing extra to run.
Click Tag to team in the Raid Summary header. Dr. H.R.T suggests the best-matching team based on roster overlap. Teams belong to your guild; register a guild and create teams under Settings.
Open Dr. H.R.T to see boss kill trends, player form, consumable compliance, and debuff uptimes charted across lockouts. Everyone in the guild can view their teams' trends, and the charts get sharper with every tagged week.
Officers can copy a read-only share link that works for anyone, no sign-in and no WCL key needed. Handy for recruits, coaches, or the guild Discord.
Sharing Results
Click the Share button in Dr. R.O.T or Dr. R.L.D to copy a link with your current report (and, in Dr. R.O.T, the selected fight and player) encoded.
Shared links are viewable by anyone, signed in or not, with or without a key. The viewer sees everything that has already been computed for that report, straight from the cache. Anything not yet computed shows a "sign in and add a key" prompt, and the search box is locked, so a shared link is read-only until the viewer adds their own WCL key. A SHARED banner makes the mode clear.
