Spheroids of Brute Force
These orbs are blue energy-based constructs which are pretty much the size of marbles. Nadine holds three of them. (For now...)
These can be destroyed, but since they are very compacted and concentrated, its hard to do that. Though, seeing as how they are small and constantly moving, you've gotta think.
These Spheroids serve two purposes...
The first purpose they serve is being an amplifier. (A loud speaker with a volume button, if you will.) The energy from Nadine travel into the Spheroids and shoot outward in a spreading, condensed beam of invisible pressure.
The second purpose is obviously a defense mechanism used in a different way which absorbs the damage and force of an attack, storing it for later use.
