hi, for the .lsb file in Data/Public/Mod_Name/Localization/
is not a good solution, because if Larian update the game like the previous patch, your object name will doesn't works anymore.
if you create a new .lsb dedicate to your mod, with same parameter in
Divinity-Original Sin\Data\Mods\YOURMODS\Localization\
no more problem with future update.
The things modified in my Localization folder are the specific variables referred to in my mod's SkillData.txt file (which doesn't override anything from the Main folder). There shouldn't be any overlap at all, unless Larian decides to implement something that requires "Summon_BraccusRex_DisplayName" etc in the future.
