I want that item in the Nightmare Land!

You can have it! There are a couple ways to target an item in Nightmare Land.

Sun Targeting
Sun will always try to Illuminate multiple interesting targets, but sometimes you want more control. If you drag any Sunburst item over a Nightmare Land tile, you can send all of its Illuminating power straight to that tile!

Nightmare Merging
Items on Nightmare Tiles can be merged in the same way as items on Illuminated tiles. Simply drag 2 or more identical items over to the item and merge them to immediately free and merge it, no sun required! Any sun you've sunk into that tile will be refunded!
