In Diablo II Resurrected, Ghostflame is part of the Legend Spike category and one of many unique Knifes in D2R. It is a relatively small item, taking 3 Blocks of space if you want to store it in the inventory or stash. Your character needs to reach at least the Required Level of 62 to carry this item. This Legend Spike has a Strength Requirement of 65 before it can be used. Another limitation is Dexterity, which should be 67 as the very minimum.
This is already the elite version of this Knife, so it cannot be upgraded any further. The normal version is called Blade, while the exceptional version is Stiletto.
Note: If this item can have sockets, you might be able to get some runes and get one of the runewords as a result - if you place them in the correct order. Have a look at our builds to find out which items make the most sense for the character you're currently playing.
