You do realize that Gjallerhorn does in fact add 2mp/tick to each ballad right? Not just 2 more total ticks? Thus adding 4mp/tick total when both ballads are on? Because thats where the relevance you are searching for exists.What relevance does that have to relic horn ?? As much relevance as an imaginary world with only 1 Ballad and no refresh....Abso-fucking-lutely nothing.
Now, once again...what exactly does Gjallarhorn do other than an extra 2 ticks on ballad and free up 15 inventory slots for a bard ??
