Thor has access to Divine Soul Magic and both him and Mjölnir are able to use Bifrost while Kratos has only Innate Soul Magic, with Divine Soul Magic via Blade of Artemis and that+Zeus' Lightning with the latter's Gauntlet...
But Kratos resists EVERYTHING... aside from Duraneg, much like the Thrúd vs Deimos (which i'd like more attention towards ;-

And while the Blade of Artemis gets basically 100% resisted aside from AP-wise, only the Gauntlet Of Zeus' Absorption is a hax with 1-C AP and something Thor doesn't immediately resists
So it's basically 2 Duraneg vs Absorption since skillwise they should be comparable
