Also, you will need to execute this in your database:

ALTER TABLE `droplist` ADD `enchant` int(5) DEFAULT -1;
ALTER TABLE `droplist` ADD `enchantChance` int(3) DEFAULT 0;

i will test...and the enchantChance option is for?

edit

java/com/l2jserver/gameserver/datatables/HerbDropTable.java

cant found HerbDropTable.java in my datatables folder...

B1ggBoss · August 20, 2011

example +3 Dynasty Earing 20% chance etc...

i though you want to add a chance to be dropped enchanted or not. anyway, if you want the item to be always dropped enchanted, just put 100 as enchantChance

xDafuQ · August 20, 2011

ah now i get it if i put 100% to drop the item and 20% enchant chance have only 20% to come enchanted...;p nice too i will use it ;D

edit

i added all code exept HerbDropTable part...i cant found it...

B1ggBoss · August 20, 2011

The patch is made for last l2jserver trunk version

xDafuQ · August 20, 2011

ok i will test without this part...

xDafuQ · August 20, 2011

well i think i make all done but ingame when i go on Add Drop on mob dont shows me option

Enchant

enchantChance...

maybe something wrong with DP part?

B1ggBoss · August 20, 2011

did not add support for adding it by admin command, just by maunally edit database

xDafuQ · August 20, 2011

hmm so i need add drop in db instead of ingame?i will try ty for help ;)

xDafuQ · August 23, 2011

dont work still drop +0...

Bleadd · August 23, 2011

Hmm i'm not sure, but like l2phx, you need to make the id of the weapon + the enchant you want and put it in the field drop.

it's just an idea!!

i dont get what you mean...

Bleadd · August 23, 2011

In l2phx, there was a bug. Was to take the id of a weapon, to add 20 to the id and send the packet to the server. And the server gave the weapon +20

Maybe here is the same principle

B1ggBoss · August 25, 2011

dont work still drop +0...

works for me
