And don't forget the fact that it's a blessed blunt weapon, which is handy.
And check out the activation!

Since we compare MoD lengths, lemme show mine:

a) the Mace of Disruption of Oiontana (11d8) (+13,+13) {!k}
Found lying on the floor in a vault at 4900 feet (level 98).

Slays animals, undead.
*Slays* demons.
Branded with weak acid.
Cannot be harmed by acid, electricity, fire, cold.

Combat info:
7.0 blows/round.
Average damage/round: 1491 vs. animals, 1491 vs. creatures not
resistant to acid, 1958.6 vs. undead, 2894.5 vs. demons, and
1023.4 vs. others.

Alas, no slay evil, and also its Feanor not Deathwreaker. It started out with crappy damage enchantment, I got it up to +13 with scrolls.

Without the +2 off weapon blows, it would be about 1065 acid, 1477 demon, 730 other.

You don't need Slay Evil when you have 11d8 base damage dice...

Since normal MoD dice is 5d8 that's 2x slay everything and then some.

Alright, I'll admit it: your one's bigger than my one.:mad:

Balrog of Moria: Feel my wrath!
You: *WHACK*
Balrog: That's just unfair. <dies>

Yeah, the demon damage is nice, but you can't ignore the Acid Brand. Hi sauron!

That's sick. What does provide +2 EA? Gloves?

When Rings of Acid still gave you brand I usually used that and MoD or BoC of Fury +2 against Sauron. 1000+ damage was not uncommon even with Priest. Against Morgoth there was some competition from other weapons, but not much (fury weapons had +25+ to_dam usually).

High-dice extra blow weapons can still be rather good even without any other bonuses, and MoD has inherit slay undead.

Body armor, and it was one of the big ones (deathwreaker or bladeturner base, dont recall which).

Its a project where some character died, I checked the artifact list and made a new one with same artifacts, playing till I found all the goodies. In a normal playthrough you dont get such a setup :P

Nonetheless, it was fun.
