This addon was inspired by and uses code derived from SymbiosisTip by Wildbreath.
Mists of Pandaria added several rare enemies that drop unique items, and 5.4's Timeless Isle continued that with countless more. Warlords of Draenor... pulled the lever to max and broke it.
This addon is intended to help you remember which NPC drops which unique item. As you mouse over an NPC, an additional tooltip for the item is shown. Timeless Isle rares often have secondary drops as well, shown in a shortened secondary tooltip.
By default, tooltips fade after being shown, unless the item is still required for an achievement. Holding Shift keeps them shown. Options are on the way! (I just suck at XML)
Now with full* Draenor data! Draenor rares drop their items with a 100% chance on the first kill, afterwards they are normal enemies. RaresTip will show when you already have defeated a rare.
Also still in: Pandaria rares, including Zandalari Warbringers (to help identify which mount they can drop) and some other NPCs, mostly from Pandaria, that drop interesting items.
I'm very open to suggestions what else could be added
