This is a guide on how to get the Spectral Tiger working 100% on your server.
First, open up navicat and go to creature_names. Then, make a new entry. Put the entry # as 24004 (It HAS to be this or it wont work) Then go to the displayid field and put 21974 (Again it HAS to be this or it wont work) Creature_proto does not matter unless you want to spawn it. Next, go to items on your server and put a new entry. Make sure it looks exactly like this or it wont work:
Entry: 33225
Class: 15
Subclass: 0
Field4 : -1
Name-name4: Reins of the Swift Spectral Tiger
Displayid : 17608
Quality : 4
Flags : 0
Buyprice : 0
Sellprice : 100
Inventory type : 0
Allowableclass : -1
Allowablerace : -1
Itemlevel : 60
Requiredlevel : 60
Requiredskill : 762
Requiredskillrank : 150
Requiredskill subrank all the way to range: 0
spellid_1 : 42777
spelltrigger_1 : 0
spellcharges_1 : -1
spellcooldown_1 to the end : 0
After that restart your server and .additem 33225. If it says World of Recall (OLD) when you try to use it, then your spell files are out of date. Get a DBC extractor and extract the latest spells. After that it should work 100%.
