The best thing about these DL forays is that Myria always makes a lot of friends. However, not all of them are very happy about Myria's endless search for happy entourages. Melfice certainly doesn't seem all that eager to be friends with anyone, and that makes the goddess very sad. But, as usual, she has just the right tool to fix those antisocial losers: even if Melfice's evasion makes Myria's attacks not very useful this time around, her Big Crash spell gets around that little factor very easily. And the insane difference in durability between the nigh-immortal goddess and the frail Horn of Valmar will mean that she'll end the battle long before Melfice even dents her noticeably. It's pretty simple, but it works!
