They matched together while they listened to their angel inform them of the material they needed to build their altar and where to get it. Their angel described a lot of difficulties they could face, but they were confident in themselves.
Legion-1 is undoubtedly their source of confidence. With his Endurance at 320, it would take a god with an Authority of 3200 using Divine Strike or a god with 320 in Strength to harm him at all.
Even if that were possible, they will not allow it to happen without interfering with Divine Spells. The addition of the use of Divine Shield will make it more difficult to harm him. But they are not eager to use divine spells at all. It is something that they will use as a last resort.
From what they can deduce, even though Divine Spells are powerful, any god seed using Divine Spells is ready to pay any price to kill their enemy, including their death. It is because Divine Spells are expensive to use.
