In Phos' Wager the outcome to the final struggle between Phos and Skotos cannot be known, but everyone ought to choose Phos in any event and bet on the good succeeding. At the end of the Phos' Creed they add:

On this we bet our very souls.

It is hinted that this view originated centuries earlier, by gambling Kalavrian merchants based on a remark made by Videssian nobleman Iakovitzes that they would even gamble on whether or not Phos would triumph over Skotos.

Namdalen is unique in its belief in Phos' Wager and viewed as heresy by Videssian Patriarchs.
