One Liam.
Three Zeniths.
Liam couldn't actually use all his abilities at the same time.
That was foolish.
He had to be smart about it.
Most of Liam's fights ran the long course.
They lasted for several minutes.
Sacrificing his precious blood, albeit there were high quantities of it, could pose a threat to his regeneration.
At the same time, Liam couldn't just use all his abilities to win a fight.
It didn't work that way.
The closest analogy would be guns.
Not every gun was used for the same situations.
Grenades and rocket launchers were used on tanks or heavily armored vehicles.
Sniper rifles were used at long range.
Rifles were used in general combat.
The same could be said for Liam's arsenal.
Corruption was used against physically powerful enemies that needed to be incapacitated.
Chaos was used against enemies that were too spell-based, or too armored.
