Cost: 25 gp

A resonating dagger has a thick, wide blade that narrows only slightly as it approaches the tip, and can only be made from the steel of a melted-down warhammer.

Light Thrown (A basic attack with a light thrown weapon uses your Dexterity. Light thrown weapons don’t deal as much damage as heavy thrown weapons, but some powers let you hurl several of them at once or in rapid succession.).
Off-Hand (An off-hand weapon is light enough that you can hold it and attack effectively with it while holding a weapon in your main hand. You can’t attack with both weapons in the same turn, unless you have a power that lets you do so, but you can attack with either weapon.).
Energized (thunder) (When you use an attack power through an energized implement, you gain a +2 bonus to damage rolls if the power has the keyword that matches the implement’s damage type. The bonus increases to +3 at 11th level and +4 at 21st level.).
Forceful (Whenever you pull, push, or slide a target with an attack power using a forceful implement, the distance of the forced movement increases by 1 square.).

Light blade (Light blades reward accuracy as much as force. Pinpoint attacks, lunges, and agile defenses are the strong points of these weapons.).
