Functions as a masterwork long sword 

Once attuned 

       -a spell caster can choose to sacrifice a spell slot giving the sword a magical plus equal to the spell level sacrificed for ten minutes. In addition while the sword is powered up by these means a successful critical hit forces the target to make a con save DC(wielders spellcasting save dc) Or the sword absorbs a spell slot equal to the swords current bonus (if applicable) giving the spell slot to the wielder 

 

       -The sword can be used as a conduit for spells allowing the caster to infuse the spells magic into the blade activating on the next attack made with the sword. If the target of the weapon is hit they get no reflex save for the spell. If the attack misses the spell still activates as normal (dm discretion) centered on the targets location however the target receives a reflex save as normal. The spell then takes effect centered on the attacked creature all other creatures that would be within the spells normal effect radius follow normal spell rules. 

 

The caster may choose to half the area of effect of a spell designating the direction the spell takes effect. 

 

In the round the spellcaster cast a spell on the blade the may make an attack as a bonus action as it is considered part of the casting action. Alternatively the caster may choose to hold the spell in the blade by making a concentration check with a DC (10 + number of rounds attempting to hold the spell). All other rules of concentration still apply to containing the spell. If concentration on the spell fails before the spell is used the magic fades harmlessly the spell slot lost.
