Mass Effect: Tech Talent: Omni-Blade

Omni-Blade
Time Taken: action
Prerequisites: Computer Programming / Repair 4D
Although melee-combat applications for the omni-tool are almost as old as the device itself, the feature was largely unused prior to the Reaper invasion. The need to take on multiple husks in close quarters forced the Alliance to develop ways to enhance the tool's offensive capability. The most common melee design is the "omni-blade," a disposable silicon-carbide weapon flash-forged by the tool's mini-fabricator. The transparent, nearly diamond-hard blade is created and suspended in a mass effect field safely away from the user's skin.
To activate the Omni-Blade you have to roll successfully for Moderate (11-15) Computer Programming / Repair skill, after that the blade materializes. You use Melee Combat skill for the operation of the blade. A standard Omni-Blade deals STR+1D damage, but larger blades are possible.
