the shell limits me to elements of that tree, the oppposite of lava (water + fire) is water (despite being used to make lava it'll turn it to stone which is more of an element shift rather than actually countering it). the opposite of time is entropy. demon fire is (death + fire) + ((water + fire) + (earth + fire)) = demonic energies/flame

Also, like I said, I don't know what your combinations are. As such, I have no clue what "elements of this tree" are. And if you mean all combinations that include Death somewhere along the line, then, as I said, that's incredibly overpowered.
