Hero weapons (NOT BUG)
 

All classic 2.0 versions:

Classic 2.0 Patch notes: https://eu.4game.com/lineage2classic/play/saviors/
Classic 2.3 Patch notes: https://eu.4game.com/lineage2classic/play/zaken/

And as you can see, the hero weapons was implemented only in 2.3~2.5, but we can have it in the 2.0.
The weapons miss some skills because we should not be able to get the weapons.

So, the option to get the weapon must be removed from the npc.
As a quick fix for my server, i'll remove all the ids from the database.

Thank you.

We are developing the game on the Russian official server. In the Russian official server, the heroic weapon was introduced in the update "Saviors".

And, perhaps in the patch-nodes, what you gave, a typo.

Not bug. Closed.
