Powers

Spell-focus

Spells can be cast through the sword with sword motions providing the somatic component and Elven song of the blade serving as the verbal component. Spell components valued less than 50 gp are provided by the sword, unless the component is the object of the spell. Spells cast through the sword have boosted effects as if cast at one level higher. The sword must be held in hand at the beginning of the round that the spell is initiated, and can only be used in defense for the duration of the casting time.

Magic Use

The sword empowers use of wizard spells.

If the wielder can already cast wizard spells, then the casting level is increased by one level.
Bards use the wizard spell casting progression table so that a 2nd level bard is treated as a 1st level wizard with the potential for accessing 6th-9th level spells if permitted my intelligence.
If the wielder doesn't already cast wizard spells, then spell casting ability is gained as a 1st level wizard.

Cantrips

A cantrip spell is in continual effect allowing the wielder or sword to generate small magical effects one per round. This includes translucent illusions, lighting and snuffing candles, small puffs of wind, inflicting coughs and sneezes, etc. 

If the wielder can cast priest spells, then orisons in the major and minor spheres of their patron deity or deities are also available. This includes blessing meals, making benedictions, taking oaths, freshening objects, etc.

Starshine

The blade can shed starshine covering an area up to 30' radius. The field can be tightened to a 6 inch radius immediately around the blade with swirling stars.

Starshine Spell Boost

Once per day, one variable aspect of a spell cast through the sword, such as damage or duration, can be boosted. The blade always sheds starshine to its maximum range before this power is used, and the star fields collapses upon the blade at the time the spell is boosted.

When the wielder then casts a spell, that spell will be enhanced so that saves against the spell are at -2.

The following variable aspects of spells can be boosted:

50% increase in area of affect
+1 per die to damage rolls
50% longer duration
50% increase in range

Feature

Near the base, just inside the lighting bolts, are 5 dark metallic five pointed stars taken from the core of a living star fallen to the ground in the Star Mounts. The stars are visible on both sides of the blade on each edge. They naturally generate and attract electricity. The metal has a natural influence on magic and usually enhances it.
