I just tried this now and it works:

• Start SkyEdit and load Skyrim.esm as normal (no active file set so you're creating a new plugin).
• Find and edit the amulet "JewelryNecklaceGold".
• Change the EditorID to "JewelryNecklaceGoldDave" (or whatever to uniquely identify it).
• Change the Name to "Gold Necklace Dave" (or whatever...).
• Save it and press "Copy" to create a new copy of the recipe.
• Find the "RecipeJewelryNecklaceGold" recipe and edit it.
• Change the EditorID to "RecipeJewelryNecklaceGold"
• Change the ResultItem to "JewelryNecklaceGoldDave"
• Save it and press "Copy" when prompted.
• Save the plugin to any desired name.
• Start the game and choose "Data Files" from the launcher first.
• Ensure the new plugin is "checked".
• Start the game and find a forge with a Gold Ingot in your inventory.
• You should see the original "Gold Necklace" along with your "Gold Necklace Dave" (or whatever you called it).

This worked for me several times just now but if it doesn't let me know at what point your running into issues. I also noted a bug in SkyEdit when using the "..." button to edit a record and copy it although this shouldn't be affecting the appearance of the item in the game (it still worked for me).

2 would be combat target (necromage is a good example perk)

And of course, thanks very much for the update!

One thing I've noticed, recipes only allow you to choose from alch, armo, misc and weap for results and components if you browse the lists, but manually typing in other itemtypes works, so maybe these could be added to the browse-function (example: you can create recipes that create or require books and arrows).

Here is what I have done and Nothing appears ...

Plus I see no entry to put the inworld item for the new jewel thing?

I tried an empty spell/effect now and it didn't crash. It could be a more complex case like if UnknownX is 3 the game expects UnknownY to be a RACE record and crashes if not, or it could be the subrecord order of the spell/effect is eventually messed up by SkyEdit. Feel free to email me the a plugin that crashes and I can take a look.

Feel free to [email="dave@uesp.net"]e-mail[/email] me the plugin and I can see what the issue is. There is no way to actually "place" items in the world with SkyEdit as that would require a full 3D world editor. You can place things into various leveled/form lists and containers though or simply use the console for testing.
