The merged patch function simply merges leveled lists together. If you go into TES5Edit and use Create Merged Patch, and check out the newly created mod, you'll see that it usually contains only Leveled Item entries. More importantly, it doesn't merge the ones you've selected; it merges all the leveled item changes in all the mods you have loaded with TES5Edit. This topic is about merging entire mods, complete with: weapons, armor, items, npcs, cell edits, potions, actor value info, recipes, container edits, combat styles, encounter zones, imagespaces, enchantments perk changes, quests, races, and more.
