That could work.
If we make one a rapier of puncturing, that's 50,320 gp. Can we enhance that further?
The equivalent enhancement isn't the big deal, I think, but I've never heard of the "specific" magic weapons being enhanced except as new "specific" weapons (if then). But maybe it's reasonable to give her unique weapons. Anyone know the rules on this?
Well, mithril chain is a specific magic armor and that's often given additional enhancements.
Anyhow, she's a unique being so I suppose there's no harm in giving her a couple of unique weapons.
That's a bit different in that it's not a magic item, per se, but a pre-made use of special materials that happens to be in the magic armor section. Still...
...I agree!
By my figuring, a +2 axiomatic puncturing rapier is approximately a +8 weapon (the puncturing is worth about a +5 including the first enhancement bonus), or 128,000 gp, and the same for the anarchic version. Is about 250,000 gp worth of weapons about right, or will we want more for other items and armor?
SRD said:Three times per day, this +2 wounding rapier allows the wielder to make a touch attack with the weapon that deals 1d6 points of Constitution damage by draining blood. Creatures immune to critical hits are immune to the Constitution damage dealt by this weapon.
Rats, forgot about that.
Sure, your suggested weapons are fine.
