Powers

Bladesong

On command, the blade can emit a humming sound. Successful hits deliver an additional 1d4 damage from sonic energy and stun the opponent for one round. A silence spell can negate the sonic damage.   

Successful hits also produce a ringing chime sound that can be clearly heard within 30'. Allies gain a +1 on their morale checks and +1 on saving throws versus fear.

One additional attack may be made per round using a standard roll to hit. The additional attack can take place at any time in the round after the first regular attack, as designated by the player at the beginning of the round. The additional attack stuns the opponent for one round, but doesn't deliver damage, unless a critical hit is made which can deliver any special attacks of the critical hit, including damage.

Those who are stunned, are not able to take any actions beyond retreating or defending themselves.

Sonic Burst

  A successful critical hit will deliver a thunderous crack that delivers 1d8 of additional damage to an opponent, who is stunned for 2 rounds and deafened for 2d4 rounds. All other combatants within 10', both friend and foe, must make a save versus paralyzation or be stunned for 1 round and deafened for 1d4 rounds. The sonic crack can dispel silence.   

Shatter

Touching the humming blade to a nonmagical object made of crystal, glass, ceramic, or porcelain, causes the item to shatter into dozens of pieces.

Dancing Lights

At will, the sword can generate up to 4 orbs of dancing lights in any color desired. They can move up to 200 yards away before winking out.

Interactions

Chopping - When the chromatic blade is active, the sword can be used to chop stone, metal and wood objects, hacking through a foot of material every round. It can cut through softer materials even faster.   
Moonblade - The dancing lights can shed moonlight.
Dweomer Drinker - The blade can temporarily absorb magic and turn it against itself to enable cutting through stoneskin or walls of force.
Flame Tongue - Dancing lights can appear as flickering candle light. They can ignite very flammable items, including oil, parchments, and dry kindling. They shed sunlight to a radius of 2 feet capable of harming creatures damaged by sunlight.

Lathander's blessing - allows the dancing lights turn rosy red to deliver a rosetouch spell once per month magically mending broken objects or stanching wounds.

Selune's blessing - allows the dancing lights to behave as motes from Presper's Moonbow once per month. The wielder can choose how many dancing lights are converted to charged motes, which will shed moonlight once converted. Unused motes need not remain near the blade wielder who is immune to electrical attacks while any motes are active, or when the blade is shedding moonlight.

Appearance

Rune

Rainbow - on front.  

Feature

Cutting edge of the sword of 1/8 inch width has been turned to clear crystalline diamond with iridescent sheen. Near the very tip, above the slits, on each side of the adamantium spike are two small triangular chips of rainbow obsidian. Rainbow obsidian is an obsidian variety in which all colors save yellow are included in the black or gray base, sometimes in pronounced bands or spangles. Its magical use is as a pass stone for prismatic magics: It can pierce the various shells of such spells without ending them or suffering harm and can bring inorganic materials that it is fastened to with it. (In other words, a rainbow obsidian-tipped weapon could strike through a prismatic wall, but a living person or undead creature wearing a rainbow obsidian ring would not escape the normal effects of the prismatic magic.)
