I am happy to find out that in the last version of TPT a new hotkey (E) was introduced, allowing you to search for elements (including secret elements and elements that you made yourself). I found a strange element called EMBR (ember) that acts fire-like, I searched for it, but it doesn't seem to be documented, would there be anyone that could tell me more about embr and if there is a way to create it (besides the element searcher) or some special use for it?
Old.
EMBR is made from exploding FIRW.
EMBR is a helper element used in place of special effects that previously used a combination of other elements, to prevent some older problems.
...It doesn't really do much by itself, though. It's basically just a graphics element that can do everything.
