Etherium's Blade

From within yourself, you draw a blade of pure magical weave. It is drawn from the chain of Etherium, that links your life-force to the weave. Your skin alights with arcane energy becoming one with the weave as your own connection creates a shimmering handle that you pull from within drawing out a blade (or small bladed weapon such as a dagger or spear). The arcane weapon is a part of you, so cannot be lost, but it will disappear if you die or dispel it. The weapon itself deals 1d6 slashing damage, and marks the target with your arcane energy signature. You can now track this target up to 300 feet from yourself until it grows too faint to discern.

The damage of the blade increases with the player's level at 5th, 11th, and 17th by 1d6.
