Where are skills, names and NPC functions strings located?

[Ogodei]

Hello guys! I'm working on the Italian language pack for Belzebub, but I've been able to find only the speech lines regarding monsters, quests and dungeon books. I couldn't find the strings related to skill names , skill descriptions, item names, item properties , NPC Functions (e.g. Repair Items or Buy Items) and so on. Could you please help me by telling me where these strings are stored? thanks in advance!
