Etherwarp Merger

 is a drop from the Voidgloom Seraph  with LVL 7+. It is used to merge Etherwarp Conduit and Aspect of the End/Aspect of the Void, giving the Etherwarp Conduit effect when used with +.

Trivia

 * While the Etherwarp Conduit requires Enderman Slayer VII to use, the merged version of the sword does not.
