Quartz Enhanced Bear?!

The bearkin lunged in response, trying to catch up to Lassim, its claws tearing through the air with ferocious speed. 

Lassim moved instinctively, the surge of fused mana in his pathways following his motion. 

With another short burst of [Lightning Steps], he sidestepped the attack, the sharp claws passing so close he could feel the displaced air on his cheek. 

The creature's momentum carried it forward, its massive frame crashing into the cavern wall, sending chunks of rock and some shards of Spirit Quartz cascading to the ground.

Lassim used the moment to strike. With a calculated pivot, he swung his halberd in a wide arc, channeling his fused mana into the rune covered blade. 

Lightning spirit fish materialized around the weapon's edge, their somewhat translucent and tentacle tails crackling with electricity as they darted toward the bearkin.
