Need help identifying an AD&D weapon... I think.

[SL33TBL1ND]

Here we go then. About 6 years ago I was in an AD&D campaign. I was playing a LE Cleric. THe DM decided to give each player a gift from their deity, my deity was Nerull. Nerull gave me a Mace that had several magical properties. I will list them below.

Powers:
1. +5 vs Humanoids.. I had to keep track of how many humanoids I killed, the DM would not tell me why
2. Did not have to eat
3. Did not have to breath
4. Did not have to sleep
5. Twice a day I could turn ethereal
6. The Mace could talk to me.. it was always telling me to kill.

Does anyone have an idea of what this Mace is called or do you think my DM just made up some weapon?

Thanks,
Nerull

Made up for the sake of story says I after reading through all my AD&D books.

Sounds certainly a made up one, the only +5 I know of is the Holy/Unholy Avenger and they're both bastard swords. The other bits sound like "borrows" from Stormbringer. Maces aren't associated with any Clerics of Death because Death Clerics are the only ones allowed to use Bladed weapons, usually.
