Item Enhancements

core 3.3.5a.

Where or how can i modify how item enhancements(armor kits, sharpening stones, etc.) work.

Example: If i wanted to change the Light Armor Kit to give +8 everytime or +10% stats instead, where to look to do this? I see in the item_template the entry for this item 2504 link to spellid 2831. Is there server side code that handles this? Or can i add a custom script to do this? I have looked at the spell_item.cpp. and item_scripts.cpp. If anyone can help me, i’m looking for a point in the right direction.

Thanks to any who can help me with this.
