Yes, sorry. It's not possible for me to edit the original post, unfortunately. This one will do it for you, though:
Code:
### This sets the Evil Eye in Guk to drop the Bag of Sewn Evil Eye 75% and Manastone 25% ###
UPDATE lootdrop_entries SET chance = 75 WHERE lootdrop_id = 18855 and item_id = 17354;
INSERT INTO lootdrop_entries VALUES (18855,13401,1,0,25);
