Sap of the Enlightened Witness and Mace of Municipal Cleanliness are both brilliant weapons :)
It seems tricky to figure out how big the weapon bonus is based on the spell level and caster level of the spell involved. After much reading over the examples on <a href="
http://www.d20srd.org/srd/magicItems/ma ... .htm">this page</a> I concluded that I have been calculating prices all wrong, so I'll have to go back and edit my previous posts.
Here is my attempt to price the Sap of the Enlightened Witness and Mace of Municipal Cleanliness
1gp for the sap
+300gp for because it is masterwork.
+8000gp because it is a +2 enchanted weapon.
+79200 (4 * 11 * 1800) for Modify Memory, Spell level 4, caster level 11, command word activation
For a grand total of 87501
However, if it is reduced to only work once per day, the Modify Memory cost gets divided by 5, to a more manageable 15840, making for a grand total of 24140gp
Then for the mace.
5 gp for the mace
+300 gp for the masterwork
+8000 gp for a +2 weapon bonus
+30000 (3 * 5 * 2000) for Meld Into Stone, spell level 3, caster level 5, use-activated.
For a grand total of 38305gp
If reduced to a single use-per-day, the total price works out to 14305gp
