Both Finnegan Honorston and Manni Fenning, being 'half-step immortals', are very clear about the strength of a half-step immortal.
The two of them teaming up could generally defeat any half-step immortal!
The reason they say "generally" is because there are exceptional cases.
As for such exceptional cases, they pertain to encounters with half-step immortals who either possess Divine Abilities that surpass those of the Worldly Plane level, or weapons that surpass the Worldly Plane weapons:
Immortal treasure!
And now, their opponent, a half-step immortal, happens to possess an Immortal treasure...
In such a situation, let alone the two of them teaming up—even if two more half-step immortals joined in, they wouldn't be enough to defeat him!
