Void Dancer

The Void Dancer subclass mixes the standard abilities of the rogue, with the ability to teleport around the battlefield. 

Void Jump

At third level, you gain the ability to cast the spell misty step. For you, the spell takes an action to cast, however it can be used an unlimited number of times.

Void Dagger

After using your Void Jump ability you can use your bonus action to launc a shard of void energy as a projectile at an enemy. The Void dagger deals 1d10+Wis  force damage and has a range of 30ft. 

You can throw two daggers at 5th level, three daggers at 11th level and four daggers at 17th level (this progression is dependent on your rogue level not your overall player level).

Void Walker

At 9th level you gain the ability to enter the realm between realms and travel great distances, but only when no gaze befalls you while you do so. 

You gain the ability to cast dimension door a number of times equal to your wisdom modifier (minimum of once), but only when no one can see you. The casting time is  an action and you can cast the spell imedietly after breaking line of sight. You regain all expended charges once you finish a long rest.

Misty Visions

Once per long rest you can force a creature you can see to make a Wisdom saving throw (your DC is 8+your proficency+your wisdom modifier). On a failed save the creature is unable to percieve your presence for 1 hour, rationalising any noise you make or movement you cause as a benign force (the wind or just bad luck). If you chose to atack the creature, he becomes aware of your presence, however he still can't see you and must mak a Wis save at the end of each of his turns to end the effect of your ability (he can only atempt this saving throw if he is aware of your presence)

Void Mastery

When you reach level 17 you atain the final insights into the power of the void.
