Killing Morgoth in Melee?

[Infinitum]

Well, he's there isn't he? Curently playing 1.41. Had pretty high hopes for my last attempt (~55 effective evasion, ~25 attack, +20 Free Action, singing Song of Freedom, Riposte+double attack) but it turned out that my Sharp Mithril Greatsword (3d9 effective strength) wasn't quite enough to overcome his last powerups regeneration.

Lowish attack score, but thought I could go with Anticipate to compensate but couldn't actually get him to become Aggressive at low hp. Thought cutting a Silmaril or two was enough, but seems I was wrong.

Realistically I did find Saithnar shortly after making my artifact sword so could have optimized a bit by foregoing the smithing and anticipation and putting a few extra points in power/attack skill, but not sure if that'd work outside of some very good RNG. Has anyone succedeed with a pure melee character in this version?
