OK I've been trying to do some modding on my server but I've hit a wall. i think it's because I'm using trinity-core repack but I'm not sure since what i want to edit isn't that complicated.

The three things I'm trying to mod are:
Add stats to bags
Change 2 Talent  spells
boost hit to some items.

Bags:
          Just trying to add some minor stats to bags such as some haste or defense rating . just to make it easier for players to take on some raids since this is a low pop server and getting groups together can be a pain.

Talent:
           Two talents I want to change are Nerves of cold steel and threat of thassarian. I want both of them to affect Two handed weapons as i have given chars the ability to learn a lesser form of Titan grip

Hit:
      Just want to boost some of the hit on some items.

I've been trying to follow some guides to adjust these values but when ever i go into my SQL data base and try to pull up the items by ID they don't show, i only see a very small selection of items/spells in the lists. all the guides tell me to look in Item_template and spell_dbc. I know the items are in the game because players have them but i don't see them when i look in my SQL data base.

I think it's because I'm using trinity core rather then compiling my own. reason for this is i don't have alot of time to redo the scripting to make sure instances and raids are working. other then the modding this version is working perfectly.

So is this a limitation I'm going to face using this kind of server. i have about 15 or so people playing locally and if i have to recompile a new server. I'm afraid raids and dungeons wont work and that players will have to start over from scratch.
