The lightning bolts broke Komin's and Lienia's barrier, but it was blocked after hitting Sanctuary of Void.
However, Athan was only left with 2% of his energy after that, which means he was only left with 200 Abyssal Void Essence. Naturally, the production was ongoing as well, so Athan consumed all of his saved-up Outrious Potency to get 3000 Abyssal Void Essence through Void Crux after two seconds.
'Damn, close call,' Athan thought while sweating because this last lightning had a very high amount of offensive soul power, which could seriously injure his soul. But fortunately, he connected his Sanctuary of Void to the Abyssal Void whirlpool.
Also, Komin and Lienia's barriers actually consumed more than 50% of the lightning bolt's power. Otherwise, Athan wouldn't be able to block those lightning bolts' power with just 16% (1600) of his Abyssal Void Essence motes.
