I've never really clobbered a piercer before.
So Up I go - as soon as I get up, an Angry Badger is coming online. Two piercers? One priest and his Badger Buddy. That's the ratio.
Well, and maybe a half-orc fighter-cleric, a human thief, and a zombie or so.
Oh, and after the badger, I begin to clobber. Here are some rolls:
14 - 5
12 - 6
20 - 5
5 - 3
15 - 2
Those are just the straight rolls, since I've forgotten all my modifiers. Maybe bump up the damage by one, since the mace is 2-7 damage; and at my new level I've got an 18 THACO, I think.
Clobber!
