Was made by a demon, god, or some other otherworldly being
Naelwyn count?
Is a demon, god, or some otherworldly being in weapon form, or trapped in a weapon
Rumor has it, Basil's a demon and part of his soul is Blaze
Cuts through nearly anything
Basil will often claim that his sword is sharp as, if not sharper, than a scalpel
Can limitlessly absorb/redirect/dispell magic or other energy
Heh, apparently what Blaze is made of is very, very magic resistant material. But it's a sword, too thin to really block anything with it....
