From D&D Wiki
the imolator is a blade forged by the demons of the fiery abyss this blade counts as a +20 serrated adimantim bastard sword that weighs as much as a short sword any one proficient with short swords or long/broad swords is proficient with this it deals piercing/slashing damage and causes 2d20 fire/necrotic damage upon a hit its damage dice are 1d20+30 without the enchantment all damage dealt is given to the player wielding it as hp and this blade can only be forged in the blood of a demon of the fiery abyss the blood heats up any metal and transform it to adimantim and as you hammer it shapes itself into this blade its crafting cost varies based on the starting mettle and gives the wilder blindsight of 50ft in a radius around the user while being held and the blade takes one ability of the last demon its slain and if another demon is slain with it you can choose to keep the current power or take one from the new one
the finished blade cost 400,000,000 gp in price only because the demons blood used to forge it is so hard to get ahold of and the blade is only available in places were one could find evil items or a black market stuff
