I have some ideas for some thingimajigies. They're mostly for TWOS.
Vivium - An element that is the main ingredient in recovery. Unlike most elements, it is not made of only up and down quarks. (This last part isn't particularly set in stone because idrk how quarks work)
Antibioacid - An acid that only disintegrates cells.
Might add more things if I come up with any.
