Seems like another round of tweaks and changes!

1st change: added "Spot" to the class skill list... because as it turns out, nobody uses search... like at all.

2nd change: made changes to the ability to reassign weapon enhancements for the athame.
"Reassigning athame augmentations can be done freely out of combat. However during combat, an athame can only be reassigned once with a DC 25 Concentration check that provokes attacks of opportunity.
At the 11th level, 16th level and the 20th level the mage blade gains an additional assignment charge to use during combat for a maximum of 4 charges to use during a single combat encounter."

3rd change: made the ability to exchange hp for magefire points at a rate of 10 HP = 1 MP from being a full-round action to being a free action. This will encourage more health siphoning to build charges during combat, even when not fighting magic casting opponents.

4th change: dropped the usage speed of magefire and spells absorbed (through the "spell retention" ability) from being standard actions to being swift. This will encourage it's use without solely relying on it to be the only damaging attack during the round. At the same time has coemption with other swift abilities like "slice through wardings" or spells effected by "Arcane spellsurge" and thus requires some thought to be put into it's use.

5th change: added bonus elemental damage to the "Slice though wardings" ability. Effective at 3rd level.
"Gain 4 points of fire, acid, cold, electric, or sonic damage to attacks made with your athame, with the damage growing to 8 points at level 10 and 12 points at level 20."

6th: Swapped the 3rd level "Ferocity of Sanguine Rage" spell for the "Ring of Blades" spell.
Mainly did this due to wanting to preventing more flat melee damage buffs in favor for something that will be useful even when the mage blade's "slice through wardings" is active while going full on caster.

7th: Moved the two bleed weapon enhancements "Wounding" and "Gory" down in enhancement cost, dropping them from 2 to 1 and 3 to 2 respectively.
Did this to encourage more "hit and run" tactics, letting the mage blade open against a tough foe by making several bleed attacks then falling bask to cast spells while the foe takes damage over time.

And lastly, changing the "murmuring" and "greater murmuring" athame enhancements to also work on melee weapons and not just shields.

Seems like that's everything.
Let me know what you think.
