Rifan has technique that would recall his weapon to him. Naturally because of that without wasting anymore timing he just threw his spear to Allen. Naturally that hold spear was coated with spiritual energy and with that the power behind that spear already increased naturally that also created a huge impact on the battle ring.
But on the other hand Allen also was an ideal and all the time he also counterattacked. Even though he using the spiritual energy cannot create energy Slash, but still while coating his sword with spiritual energy he was now countering the attack coming from his opponent.
