So basically it's like a lightsaber but not as hot. I was thinking of it being like the sword Hicup from How To Train Your Dragon made in the netflix original show that takes place in between HtTYD 1 & 2. It works by using monstrous nightmare gel along the middle that when lit sets the sword ablaze. It can cut through some pretty thick stuff so I should work to melt through amour. Maybe this can he a timed thing that has to charge up like all the others before it can be used. It should have the best weight since in the show it is made out of metal that is as strong as pure steel but as light as something like tin foil. In the show this metal is called gronkel iron which is not a cheap thing to make since you have to tame a gronkel or risk dying to one. So it should be pretty expensive, meant for late game.
