Jerr, read this post. Then keep reading it, again and again, until you understand it.

A Warhammer +1 grants a -1 bonus to THAC0, a +1 bonus to damage, and can hit creatures that are vulnerable to Normal and +1 weapons.

A Warhammer +2 grants a -2 bonus to THAC0, a +2 bonus to damage, and can hit creatures that are vulnerable to Normal, +1, and +2 weapons.

A Warhammer +3 grants a -3 bonus to THAC0, a +3 bonus to damage, and can hit creatures that are vulnerable to Normal, +1, +2, and +3 weapons.

A Warhammer +4 grants a -4 bonus to THAC0, a +4 bonus to damage, and can hit creatures that are vulnerable to Normal, +1, +2, +4 and +4 weapons.

The Warhammer+1, +4 vs. Giantkin is NOT a Warhammer+1 or a Warhammer+4. It always strikes as a +4 weapon, but grants the THAC0 and Damage bonuses of a +1 weapon. The only time it behaves exactly like a regular Warhammer+4 is when you are fighting what the game treats as "Giantkin."

Yes, I'm in a bad mood.
