It's not in my bags! I can't find it! Who do I pass it to?

Never mind... wipe it up.

These are exactly the problems TaintedCore is designed to solve during the Lady Vashj encounter.

TaintedCore helps players move the Tainted Core to the correct Shield Generator as quickly and simply as possible.

Using its built-in Heavy Leather Ball test mode, the addon learns which players can reach each other. When a player standing at a Shield Generator clicks "At Generator", TaintedCore automatically determines whether the current holder can make a direct pass or whether the core needs to be relayed through another player.

If you are holding the Tainted Core, the addon will flash an icon showing exactly who to pass it to. Simply click the flashing icon to complete the pass.

If a relay player is needed, that player's icon will begin flashing when they receive the core, telling them who to pass it to next.

No targeting.
No searching for names.
No guessing.
No confusion.

Just watch for the flashing icon and click it.

TaintedCore handles the routing so your raid can focus on the encounter.

TaintedCore v4.2.5beta README included. Suggested read.

Early Beta - Core Functionality Implemented, Full Raid Validation Needed
This version has been heavily tested in small-group and Heavy Leather Ball simulations, but still requires validation in a full 25-player Lady Vashj raid.
Most core functionality has been verified through simulation testing and controlled small tests. The largest remaining unknown is real Tainted Core behavior during a live Lady Vashj encounter.
This is a beta release. Additional improvements, bug fixes, and quality-of-life features are planned after full raid testing and player feedback..

4.2.5

Removed /run fallback macro when no Pass To target is assigned.
Eliminated potential Blizzard DANGEROUS_SCRIPTS_WARNING false-positive caused by generated /run macro text.
No changes to bridge routing, Final Toss Target, At Generator logic, or Heavy Leather Ball testing workflow.

4.23 to 4.24 changes

Added bridge-pass guidance to the alert system for multi-hop Tainted Core routing.
Alert now displays Next Pass / Bridge Pass recommendations when the core holder cannot directly reach the Final Toss Target.
Status text updated to show CLICK ICON - BRIDGE PASS for bridge-routing scenarios.
At Generator display updated to indicate routing via bridge when intermediate passes are required.
Improved visibility of multi-player pass chains (example: D → C → B → A).
Preserved existing Approved Players → Final Toss Target → At Generator workflow.
No changes to RL/Assist permissions, saved groups, Final Toss Target logic, or Heavy Leather Ball test mode.

TaintedCore Recent Changes (Latest Routing Development) v4.2.3

Replaced chain-order dependence with actual reachability-based routing.
Added bridge routing so the addon can recommend a middle player when the final target is out of range.
Added multi-hop routing (Holder → Bridge → Final Target).
Added route reachability learning between approved players using addon communications.
Added FINALCLEAR synchronization so all clients know when a successful delivery completes.
Fixed relay completion handling so bridge passes continue correctly to the final target.
Improved route logging to show holder, bridge, final target, and routing decisions.
Fixed false post-delivery holder-change logging after successful final delivery.
Cleaned duplicate route reset / At Generator log spam after successful completion.
Added "Searching for Route" behavior so temporary route discovery no longer appears as an immediate routing failure.

Current verified workflow:

Approved Players → Reachability Learning → Bridge Selection → Multi-Hop Routing → Final Delivery → FINALCLEAR Sync → Clean Reset ✔
