(3.3.5a) How to increase drop rate of all quest items?

Ideally would like to know if there is a way to increase all quest item drop rates to 100%.

But I have been trying to do this individually by examining the loot template tabs and referenced loot templates to try and find the specific quest item. (Using Navicat). However I Can’t seem to find the item when I search for it’s ID (Embalming Ichor, ID:2834) so I have no idea how to modify its drop chance.

Similarly certain mobs I am unable to find in the database which are in game (E.g. Rot Hide Graverobber, ID:1941, which drop the Embalming Ichor needed for the quest)

What’s the problem?

[FONT=arial]If you want to set all the quest item drop chance to 100% then… [/FONT][FONT=courier new]UPDATE creature_loot_template SET Chance=100 WHERE QuestRequired=1; – do the same for the other loot tables[/FONT]
