As Luna saw the bladespear aiming for her, she quickly reached for her sword to parry the blow.  Luckily, Niall helped cover for her in that respect so she focus more of her energy elsewhere.  Particularly?  Preventing her head from being lopped off in a single blow.    She raised her shield to quickly block the slash of the thin blade heading for her neck, moving it along with the slash to make sure she wasn't knocked back from the creature's monstrous strength.  She twisted her side closest to the spear so her body would be perpendicular to where the spear was redirected from Niall to give a wider berth from her abdomen and reduce area for her to be hit.

The knightess slid her front foot forward a half step and the hand on her blade's hilt pulled the weapon free from it's sheath and up towards the Fomorian's hand wielding the spear.  The blade of her weapon shined a golden light as she instilled an amount of magic in it, hoping to take the Fomorian's upper arm with the swing.  One less appendage was something to be thankful for when this monster had many of them. Worst case, it would help deflect the Fomorian's weapon even more.
